ERROR: Cause: unable to find valid certification path to requested target终极解决方法

##ERROR: Cause: unable to find valid certification path to requested target终极解决方法各位兄弟，觉得我的方法有用，可以赞我一下的呦如果你是和我一样安装完Android studio，运行第一个Android程序，发现下面一直报这个错误。那么你可以看一下我的解决方法，既简单又直接。遇到这个问题的时候，我在去网上找解决办法：有下载证书的，有改host的，有改gradle. build的… 各种方法都试了个遍，发现并没有什么用。卸了重装，重装了好几遍也没什么用。前前后后几天也没弄出来。最后我的解决方法就是：先点

Based on the following story, continue the story by writing two paragraphs, paragraph 1 beginning with "A few weeks later, I went to the farm again. " and paragraph 2 beginning with "I was just about to leave when the hummingbird appeared."respectively with 150 words. I was invited to a cookout on an old friend's farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years.A noise at a window caught my attention，so I entered it. It was a hummingbird，desperately trying to escape. She was covered in spider-webs and was barely able to move her wings. She ceased her struggle the instant I picked her up. With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside,closing the door securely behind me. When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes.I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly.Perhaps she had been struggling against the window too long and was too tired? Or too thirsty? As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away. Hovering，she approached within six inches of my face. For a very long moment，this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight. During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say good-bye.”

A few weeks later, I went to the farm again. I was eager to see if the broken window had been repaired, and if the hummingbird was still around. When I arrived, I saw that the window was indeed fixed ...

AttributeError: 'Token' object has no attribute 'test' The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error. To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side. You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

To troubleshoot this, you should try to identify where the "Token" object is being used in your code and see if there is any code trying to access a "test" attribute on it. It's possible that you may...

John is going on a fishing trip. He has h hours available (1 <= h <= 16), and there are n lakes in the area (2 <= n <= 25) all reachable along a single, one-way road. John starts at lake 1, but he can finish at any lake he wants. He can only travel from one lake to the next one, but he does not have to stop at any lake unless he wishes to. For each i = 1,...,n - 1, the number of 5-minute intervals it takes to travel from lake i to lake i + 1 is denoted ti (0 < ti <=192). For example, t3 = 4 means that it takes 20 minutes to travel from lake 3 to lake 4. To help plan his fishing trip, John has gathered some information about the lakes. For each lake i, the number of fish expected to be caught in the initial 5 minutes, denoted fi( fi >= 0 ), is known. Each 5 minutes of fishing decreases the number of fish expected to be caught in the next 5-minute interval by a constant rate of di (di >= 0). If the number of fish expected to be caught in an interval is less than or equal to di , there will be no more fish left in the lake in the next interval. To simplify the planning, John assumes that no one else will be fishing at the lakes to affect the number of fish he expects to catch. Write a program to help John plan his fishing trip to maximize the number of fish expected to be caught. The number of minutes spent at each lake must be a multiple of 5.这道题的分析

Vika and her friends went shopping in a mall, which can be represented as a rectangular grid of rooms with sides of length n and m. Each room has coordinates (a, b), where 1 ≤ a ≤ n, 1 ≤ b ≤ m. Thus we call a hall with coordinates (c, d) a neighbouring for it if ｜a-c｜+|b-d｜=1.Tired of empty fashion talks, Vika decided to sneak away unnoticed. But since she hasn't had a chance to visit one of the shops yet, she doesn't want to leave the mall. After a while, her friends noticed Vika's disappearance and started looking for her.Currently, Vika is in a room with coordinates (z, y), and her k friends are in rooms with coordinates (x1, Y1), (x2, 32),..,(ük) 3k).respectively. The coordinates can coincide. Note that all the girls must move to the neighbouring rooms.Every minute, first Vika moves to one of the adjacent to the side rooms of her choice, and then each friend (seeing Vika's choice) also chooses one of the adjacent rooms to move to.If at the end of the minute (that is, after all the girls have moved on to the neighbouring rooms) at least one friend is in the same room as Vika, she is caught and all the other friends are called.Tell us, can Vika run away from her annoying friends forever, or will she have to continue listening to empty fashion talks after some time?如果能不被抓住输出yes，否则输出no，给出c++代码及中文解释

下面有篇英文课文，请编程找出课文中所有的单词，统计单词出现的次数，统计时不区分字母的大小写，最后按出现的次数从大到小显示出现3次以上各个单词及次数。例如，结果显示如下： the 18 a 14 puma 9 in 8 it 8 ...（略）英文课文如下： Pumas are large, cat-like animals which are found in America. When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar. The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat' only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered. The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of 'cat-like noises' at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from ? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.

使用BFS算法完成以下问题：Angel was caught by the MOLIGPY! He was put in prison by Moligpy. The prison is described as a N * M (N, M <= 200) matrix. There are WALLs, ROADs, and GUARDs in the prison. Angel's friends want to save Angel. Their task is: approach Angel. We assume that "approach Angel" is to get to the position where Angel stays. When there's a guard in the grid, we must kill him (or her?) to move into the grid. We assume that we moving up, down, right, left takes us 1 unit time, and killing a guard takes 1 unit time, too. And we are strong enough to kill all the guards. You have to calculate the minimal time to approach Angel. (We can move only UP, DOWN, LEFT and RIGHT, to the neighbor grid within bound, of course.) Input First line contains two integers stand for N and M. Then N lines follows, every line has M characters. "." stands for road, "a" stands for Angel, and "r" stands for each of Angel's friend. Process to the end of the file. Output For each test case, your program should output a single integer, standing for the minimal time needed. If such a number does no exist, you should output a line containing "Poor ANGEL has to stay in the prison all his life."

最后如果没有找到终点，则说明无法到达，输出 "Poor ANGEL has to stay in the prison all his life."。具体实现可以按照以下步骤进行： 1. 读入输入数据，找到起点和终点，并标记出所有的墙和警卫。 2. 使用 ...

In this exercise you will create a program to read text from standard input and write it to a file with each line prefixed with a line-number count. This file will be specified by a command-line argument. Directions Create a program called TestLineNumbering that accepts one command-line argument, the name of a file. Your code should verify that the command-line argument was specified. Declare a variable that holds a File object that is initialized from the file named in the first command-line argument. Within a try-catch block, create a buffered, input stream reader based on the System.in stream (standard input). Also, create a print file writer based on the File variable. Write the while loop that reads each line from the console input stream and prints the line out to the file. Each line should be prepended with the count of the line number. Make sure to close the I/O streams.

The program reads each line from standard input, increments a line number counter, and writes the line with the line number prefix to the output file. Finally, the I/O streams are closed, and any ...
