The input consists of an integer N . ( 2 ≤ N ≤ 10 9 ) Output the factorization of N using a equality. The left hand side of the equality is N while the right hand side should be a list of prime(s), from small to large, with the multiplication operator * between them.

Sure, I understand your question. Here's the factorization of N using prime factorization: N = p1^a1 * p2^a2 * ... * pk^ak where p1, p2, ..., pk are prime numbers and a1, a2, ..., ak are their respective powers. To find the prime factors of N, we can use a simple algorithm called trial division. Here's the Python code for the algorithm: ``` def prime_factors(n): i = 2 factors = [] while i * i <= n: if n % i: i += 1 else: n //= i factors.append(i) if n > 1: factors.append(n) return factors ``` This function takes an integer n as input and returns a list of its prime factors. We start with 2 as the smallest prime number and divide n by i as long as it's divisible without a remainder. If it's not, we increment i by 1 and try again. Once we've found a prime factor, we append it to the list of factors and continue with the remaining part of n. If n is not 1 at the end of the loop, we add it as a factor as well. Using this function, we can easily factorize any integer N into its prime factors. Here's an example: ``` N = 36 factors = prime_factors(N) print(factors) ``` Output: ``` [2, 2, 3, 3] ``` So the factorization of 36 is 2^2 * 3^2.

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

You have two binary strings � a and � b of length � n. You would like to make all the elements of both strings equal to 0 0. Unfortunately, you can modify the contents of these strings using only the following operation: You choose two indices � l and � r ( 1 ≤ � ≤ � ≤ � 1≤l≤r≤n); For every � i that respects � ≤ � ≤ � l≤i≤r, change � � a i ​ to the opposite. That is, � � : = 1 − � � a i ​ :=1−a i ​ ; For every � i that respects either 1 ≤ � < � 1≤i<l or � < � ≤ � r<i≤n, change � � b i ​ to the opposite. That is, � � : = 1 − � � b i ​ :=1−b i ​ . Your task is to determine if this is possible, and if it is, to find such an appropriate chain of operations. The number of operations should not exceed � + 5 n+5. It can be proven that if such chain of operations exists, one exists with at most � + 5 n+5 operations. Input Each test consists of multiple test cases. The first line contains a single integer � t ( 1 ≤ � ≤ 1 0 5 1≤t≤10 5 ) — the number of test cases. The description of test cases follows. The first line of each test case contains a single integer � n ( 2 ≤ � ≤ 2 ⋅ 1 0 5 2≤n≤2⋅10 5 ) — the length of the strings. The second line of each test case contains a binary string � a, consisting only of characters 0 and 1, of length � n. The third line of each test case contains a binary string � b, consisting only of characters 0 and 1, of length � n. It is guaranteed that sum of � n over all test cases doesn't exceed 2 ⋅ 1 0 5 2⋅10 5 . Output For each testcase, print first "YES" if it's possible to make all the elements of both strings equal to 0 0. Otherwise, print "NO". If the answer is "YES", on the next line print a single integer � k ( 0 ≤ � ≤ � + 5 0≤k≤n+5) — the number of operations. Then � k lines follows, each contains two integers � l and � r ( 1 ≤ � ≤ � ≤ � 1≤l≤r≤n) — the description of the operation. If there are several correct answers, print any of them.
