以下是用C语言编写的代码,实现对多组输入数据进行排序并输出结果: ``` #include <stdio.h> #include <stdlib.h> int cmp(const void *a, const void *b) { return (*(int *)a - *(int *)b); } int main() { int T, N, i, j; scanf("%d", &T); while (T--) { scanf("%d", &N); int a[N]; for (i = 0; i < N; i++) { scanf("%d", &a[i]); } qsort(a, N, sizeof(int), cmp); for (i = 0; i < N; i++) { printf("%d ", a[i]); } printf("\n"); } return 0; } ``` 代码解析: 1. 首先读入测试数据组数T; 2. 对于每一组测试数据,先读入该组数据中数字的个数N,然后读入N个整数存放在数组a中; 3. 调用C标准库中的qsort函数对数组a进行升序排序,排序使用到了一个自定义的比较函数cmp; 4. 最后输出排序后的结果。 其中自定义的比较函数cmp是用来告诉qsort函数如何进行排序的,该函数的实现方式是比较两个数的大小,如果a小于b,返回负数;如果a等于b,返回0;如果a大于b,返回正数。在本题中,我们只需要比较整数的大小,所以可以直接使用a-b的方式进行比较。

Solve the problem with c++ code, and give your code: Ack Country has N cities connected by M one-way channels. The cities occupied by the rebels are numbered 1, while the capital of Ack country is numbered N. In order to reduce the loss of effective force, you are permitted to use self-propelled bombers for this task. Any bomber enters the capital, your job is done. This seems simple enough, but the only difficulty is that many cities in Ack Country are covered by shields. If a city is protected by a shield, all shield generators that maintain the shield need to be destroyed before the bomber can enter or pass through the city. Fortunately, we know the cities where all the shield generators are located, and which cities' shields are being charged. If the bomber enters a city, all of its shield generators can be destroyed instantly. You can release any number of Bombermen and execute any command at the same time, but it takes time for bombermen to pass through the roads between cities. Please figure out how soon you can blow up Ack Nation's capital. The clock is ticking. Input: Two positive integers N,M in the first row. The next M lines, each with three positive integers, indicate that there is a road leading from the city to the city. It takes w time for the bomber to cross this road. Then N lines, each describing a city's shield. The first is a positive integer n, representing the number of shield generators that maintain shields in the city. Then n_i city numbers between 1 and N, indicating the location of each shield generator. In other words, if your bomber needs to enter the city, the bomber needs to enter all the entered cities in advance. If n_i=0, the city has no shields. Guarantee n_i=0.Output: a positive integer, the minimum time to blow up the capital. e.g., Input: 6 6 1 2 1 1 4 3 2 3 3 2 5 2 4 6 2 5 3 2 0 0 0 1 3 0 2 3 5, Output: 6.

Problem B Double Rainbow Time Limit: 1 Second Let 𝑃 be a set of 𝑛 points on the 𝑥-axis and each of the points is colored with one of the colors 1,2, . . . , 𝑘. For each color 𝑖 of the 𝑘 colors, there is at least one point in 𝑃 which is colored with 𝑖. For a set 𝑃 ′ of consecutive points from 𝑃, if both 𝑃 ′ and 𝑃 ∖ 𝑃 ′ contain at least one point of each color, then we say that 𝑃 ′ makes a double rainbow. See the below figure as an example. The set 𝑃 consists of ten points and each of the points is colored by one of the colors 1, 2, 3, and 4. The set 𝑃 ′ of the five consecutive points contained in the rectangle makes a double rainbow. Given a set 𝑃 of points and the number 𝑘 of colors as input, write a program that computes and prints out the minimum size of 𝑃 ′ that makes a double rainbow. Input Your program is to read from standard input. The input starts with a line containing two integers 𝑛 and 𝑘 (1 ≤ 𝑘 ≤ 𝑛 ≤ 10,000), where 𝑛 is the number of the points in 𝑃 and 𝑘 is the number of the colors. Each of the following 𝑛 lines consists of an integer from 1 to 𝑘, inclusively, and the 𝑖-th line corresponds to the color of the 𝑖-th point of 𝑃 from the left. Output Your program is to write to standard output. Print exactly one line. The line should contain the minimum size of 𝑃 ′ that makes a double rainbow. If there is no such 𝑃 ′ , print 0. The following shows sample input and output for two test cases. 具体步骤

用C语言解决下列问题:Kirill wants to weave the very beautiful blanket consisting of n×m of the same size square patches of some colors. He matched some non-negative integer to each color. Thus, in our problem, the blanket can be considered a B matrix of size n×m consisting of non-negative integers. Kirill considers that the blanket is very beautiful, if for each submatrix A of size 4×4 of the matrix B is true: A11⊕A12⊕A21⊕A22=A33⊕A34⊕A43⊕A44, A13⊕A14⊕A23⊕A24=A31⊕A32⊕A41⊕A42, where ⊕ means bitwise exclusive OR Kirill asks you to help her weave a very beautiful blanket, and as colorful as possible! He gives you two integers n and m . Your task is to generate a matrix B of size n×m , which corresponds to a very beautiful blanket and in which the number of different numbers maximized. Input The first line of input data contains one integer number t (1≤t≤1000 ) — the number of test cases. The single line of each test case contains two integers n and m (4≤n,m≤200) — the size of matrix B . It is guaranteed that the sum of n⋅m does not exceed 2⋅105 . Output For each test case, in first line output one integer cnt (1≤cnt≤n⋅m) — the maximum number of different numbers in the matrix. Then output the matrix B (0≤Bij<263) of size n×m . If there are several correct matrices, it is allowed to output any one. It can be shown that if there exists a matrix with an optimal number of distinct numbers, then there exists among suitable matrices such a B that (0≤Bij<263) .

Robert is a famous engineer. One day he was given a task by his boss. The background of the task was the following: Given a map consisting of square blocks. There were three kinds of blocks: Wall, Grass, and Empty. His boss wanted to place as many robots as possible in the map. Each robot held a laser weapon which could shoot to four directions (north, east, south, west) simultaneously. A robot had to stay at the block where it was initially placed all the time and to keep firing all the time. The laser beams certainly could pass the grid of Grass, but could not pass the grid of Wall. A robot could only be placed in an Empty block. Surely the boss would not want to see one robot hurting another. In other words, two robots must not be placed in one line (horizontally or vertically) unless there is a Wall between them. Now that you are such a smart programmer and one of Robert's best friends, He is asking you to help him solving this problem. That is, given the description of a map, compute the maximum number of robots that can be placed in the map. Input The first line contains an integer T (<= 11) which is the number of test cases. For each test case, the first line contains two integers m and n (1<= m, n <=50) which are the row and column sizes of the map. Then m lines follow, each contains n characters of '#', '', or 'o' which represent Wall, Grass, and Empty, respectively. Output For each test case, first output the case number in one line, in the format: "Case :id" where id is the test case number, counting from 1. In the second line just output the maximum number of robots that can be placed in that map.

用c++和segment tree解决下述问题Doing Exercises 描述 As we all know, the lines of students doing exercises between classes are always unsatisfactory to teachers. Today, a teacher wants to require something new. Firstly, he lets some students of N classes correspondingly form n lines. Then, he randomly selects a class to add some of its remaining students to its line, or selects a class to let some students leave its line, or lets the monitors from some adjacent classes report the total number of students in all these classes. This is very annoying for the monitors. Can you write a program to help them complete the reporting task? 输入 The first line is an integer T (T<50), the number of test cases. For each test case, its first line is an integer N (1<=N<=50000), representing the number of classes, and its second line include N integers (a1, a2, a3, ... , an), and ai (1<=ai<=100) means the number of students in the line of class i at the beginning. Then, each next line will be an order. There are 4 kinds of orders: (1) "Add x i" means adding x students to the line of class i; (2) "Sub x i" means that x students leave the line of class i; (3) "Query i j" means that the monitors from class i to class j report the teacher the total number (sum) of students in their classes at that moment (i<j); (4) "End" means ending the exercises, which will only appear at the end of each test case. The number of orders will not exceed 40000. The number of students in any line will never below 0. 输出 For each test case, you must print "Case i:" in the first line. Then for each Query, print the result in one line.

1444. Elephpotamus Time limit: 0.5 second Memory limit: 64 MB Harry Potter is taking an examination in Care for Magical Creatures. His task is to feed a dwarf elephpotamus. Harry remembers that elephpotamuses are very straightforward and imperturbable. In fact, they are so straightforward that always move along a straight line and they are so imperturbable that only move when attracted by something really tasty. In addition, if an elephpotamus stumbles into a chain of its own footprints, it falls into a stupor and refuses to go anywhere. According to Hagrid, elephpotamuses usually get back home moving along their footprints. This is why they never cross them, otherwise they may get lost. When an elephpotamus sees its footprints, it tries to remember in detail all its movements since leaving home (this is also the reason why they move along straight lines only, this way it is easier to memorize). Basing on this information, the animal calculates in which direction its burrow is situated, then turns and goes straight to it. It takes some (rather large) time for an elephpotamus to perform these calculations. And what some ignoramuses recognize as a stupor is in fact a demonstration of outstanding calculating abilities of this wonderful, though a bit slow-witted creature. Elephpotamuses' favorite dainty is elephant pumpkins, and some of such pumpkins grow on the lawn where Harry is to take his exam. At the start of the exam, Hagrid will drag the elephpotamus to one of the pumpkins. Having fed the animal with a pumpkin, Harry can direct it to any of the remaining pumpkins. In order to pass the exam, Harry must lead the elephpotamus so that it eats as many pumpkins as possible before it comes across its footprints. Input The first input line contains the number of pumpkins on the lawn N (3 ≤ N ≤ 30000). The pumpkins are numbered from 1 to N, the number one being assigned to the pumpkin to which the animal is brought at the start of the trial. In the next N lines, the coordinates of the pumpkins are given in the order corresponding to their numbers. All the coordinates are integers in the range from −1000 to 1000. It is guaranteed that there are no two pumpkins at the same location and there is no straight line passing through all the pumpkins. Output In the first line write the maximal number K of pumpkins that can be fed to the elephpotamus. In the next K lines, output the order in which the animal will eat them, giving one number in a line. The first number in this sequence must always be 1.写一段Java完成此目的
