It seems a little pitfall. I open the array to 1010, and the result times out. I changed it to 101! Bored !!! "XOR" appears in the question. I didn't understand it when I read the question. Later, Baidu gave me an explanation of "different or ~~~~ A

Use the XOR algorithm to share data in the PHPMySQL application. The XOR algorithm principle is based on the encryption method. the location change method is too simple, especially when the amount of data is small, it is easy to guess the plaintext

Some data structure ideas (1) and data structure ideas Find the maximum k value of a single-chain table At the beginning, I thought of a stupid method. First, I traverse a single-chain table, calculate the length of the single-chain table len, and

The number appears only once in the array, and the number appears in the arrayDescription:In an integer array, all numbers except two appear twice. Write a program to find the numbers that appear only once. Idea: first look at a simple instance. If

The authcode function can be said to have made significant contributions to the PHP field in China. Including kangsheng's own products, and most Chinese companies that use PHP use this function for encryption. authcode uses the exclusive or
