推荐答案

使用移位运算符可以将数字x除以2的幂.
就像
n<< 1 = n/次幂(2,1);
n<< 2 = n/power(2,2);
n<< 3 = n/power(2,3);

using shift operator you can divide a number x by the power of 2.
like
n << 1 = n/power(2,1);
n << 2 = n/power(2,2);
n << 3 = n/power(2,3);

int n = 1600;
    // n >> 1 = n / pow(2,1)
    n = n>>1; // 800
    n = n>>1; // 400
    n = n>>1; // 200
    n = n>>1; // 100
    n = n>>1; // 50
    n = n>>1; // 25

    n = 1600;
    // n >> 2 = n / pow(2,2)
    n = n>>2; // 400
    n = n>>2; // 100
    n = n>>2; // 25
    n = n>>2; // 6
    n = n>>2; // 1
    n = n>>2; // 0

    n = 1600;
    // n >> 3 = n / pow(2,3)
    n = n>>3; // 200
    n = n>>3; // 8
    n = n>>3; // 1
    n = n>>3; // 0
