exclusive or operation

1. Common Code for decimal number Commonly used code of the decimal number includes 8421bcd code, remaining 3 code, and Gray code. The encoding principle is to convert the decimal 0 ~ 9. Each of the 10 Base numbers uses a 4-bit binary code instead

There are two kinds of operations to give a sequence. One is to calculate the sum of L to R, the other is to make all the numbers of L to R and X do the exclusive or operation. Practice: Obviously, direct violence is impossible (but when this

Method 1: 1 int A = 3; 2 int B = 5; 3 A = a + B; 4 B = A-B; 5 A = A-B; Disadvantage: If a and B are large numbers, they may overflow easily. Method 2: Int A = 3; int B = 5; A = a ^ B; B = a ^ B; A = a ^ B; "^" Is an exclusive or operation, so

I wrote an article a few days ago to exchange two arbitrary types of variables using the exclusive or operation in the C language, which is based on the algorithm of using ^ to exchange two integers: a ^= b;b ^= a;a ^= b; If you understand this

There are two variables A and B, which exchange the values of these two variables. Method 1 use intermediate Variables Void swap (int * a, int * B) {int temp = 0; temp = * A; * A = * B; * B = temp ;} Method 2 does not apply to any intermediate
