普通方法从小到大排序3个数

#include <stdio.h>
int main() {
  int min, mid, max, t;
  scanf("%d%d%d", &min, &mid, &max);
  if (min > mid) {
    t = min;
    min = mid;
    mid = t;
  }
  if (min > max) {
    t = min;
    min = max;
    max = t;
  }
  if (mid > max) {
    t = mid;
    mid = max;
    max = t;
  }
  printf("%d %d %d", min, mid, max);
  return 0;
}
