使用二分支嵌套实现输入三个整数x、y、z，把这三个数由小到大输出。用C语言写代码

#include <stdio.h>

int main() {
    int x, y, z;
    scanf("%d %d %d", &x, &y, &z);
    int tmp;
    if (x > y) {
        tmp = x;
        x = y;
        y = tmp;
    }
    if (x > z) {
        tmp = x;
        x = z;
        z = tmp;
    }
    if (y > z) {
        tmp = y;
        y = z;
        z = tmp;
    }
    printf("%d %d %d\n", x, y, z);
    return 0;
}
