Operations ^ in C ++ Make good use of exceptions or produce amazing results. The nature of the exclusive or operation: Any number is different or it is equal to 0. That is to say, if we change from start to end or every number in the array, the

From: http://blog.csdn.net/wodewe/article/details/6863753 #   Question: There are n + 2 numbers, N numbers appear even, and 2 numbers appear odd (these two numbers are not equal). The space complexity of O (1) is used, find the two numbers. You

 In-depth understanding of bitwise XOR Operators The two values involved in the operation. If the two bits are the same, the result is 0. Otherwise, the result is 1.That is:0 ^ 0 = 0,1 ^ 0 = 1,0 ^ 1 = 1,1 ^ 1 = 0Three Characteristics of bitwise XOR:(

I have prepared to write a string series of interview questions for a long time. I have already written about a dozen questions, but I found that the article is so long that I have no patience to read it myself, simply split it into several series,
