exclusive or operation

When I was in a company, it looked very bad, that is, the state of an object is represented by Int. Personal perception mainly has the following shortcomings. Advantages of enumeration: 1. Although int is a strong type in C #, Int Is not a strong

It is a binary-based bitwise operation that is expressed by the symbol XOR or ^.AlgorithmIt is the binary bit of the number on both sides of the operator. Take 0 for the same value and 1 for the same value. It differs from a Boolean operation in

When I first went to the company for a written test a few days ago, I ran into several bitwise operations. I was just reading C ++ primer and happened to see bitwise operations. So I went online to search for the next article. Article To study it!

Our practice is usually (especially in the learning phase): to define a new variable and use it for exchange. The Code is as follows: int A, B; A = 10; B = 15; Int T; T = A; A = B; B = T; This algorithm is easy to understand and is especially

LeetCode 260 Single Number III (only the Number III appears once )(*)Original Given a numeric array nums, two elements appear only once, and all other elements appear twice. Find the two elements that appear only once. For example, if nums = [1, 2, 1

Here we implement suchAlgorithm: The addition, subtraction, multiplication, and Division operations are not used. Only bitwise operations are used to add and subtract integers. Principle: The exclusive or operation also becomes a semi-addition. In

I have encountered an integer that counts the number of 1 in its binary. To put it bluntly, I used recursive calls to divide the remainder by 2 and determine the remainder. If it is 1, Count ++; otherwise, Count remains unchanged. Although the
