如果有题目要求整数A和B二进制表示中多少位是不同的? 那我们要先考虑一个unsigned类型中变量1的个数?我们可以考虑简单的移位运算,向右移位,我们进行判断如果不是1直接丢掉,使用&运算符即可. int count(unsigned A) { int num = 0; while(A){ num += A & 0x01; A >>= 1; } return num } 由此,比较两个整数二进制表示中有多少不同,先将两数进行异或运算A^B,相同的位就变成0了,然后用上述方法统计
求整数最大的连续0的个数 A binary gap within a positive integer N is any maximal sequence of consecutive zeros that is surrounded by ones at both ends in the binary representation of N. For example, number 9 has binary representation 1001 and contains a binary g
