A

h, b = map(int, input().split())
if b > h:
  print(0)
else:
  print(h - b)

B

x = int(input())
n = int(input())
lst = list(map(int, input().split(" ")))
vis = []
for i in range(n):
    vis.append(0)
q = int(input())
for i in range(q):
    p = int(input())
    if vis[p - 1] == 0:
        vis[p - 1] = 1
        x += lst[p - 1]
    else:
        vis[p - 1] = 0
        x -= lst[p - 1]
    print(x)

觉得会掉分……毕竟才做对1题

A

#include <bits/stdc++.h>
using namespace std;
int main() {
  int a, b, c;
  cin >> a >> b >> c;
  cout << max(max(a, b), c)
  << a + b + c - (max(max(a, b), c) + min(min(a, b), c))
  << min(min(a, b), c);
  return 0;
}

B

#include <bits/stdc++.h>
using namespace std;
int main() {
  char a, b, c;
  cin >> a >> b >> c;
  if (b == '0' && c == '0') 
    cout << a << b << c;
  else if (b == '0' && a <= c)
    cout << a << b << c;
  else if (c == '0' && a <= b)
    cout << a << c << b;
  else {
    if (a >= b && a >= c && b >= c)
      cout << c << b << a;
    else if (a >= b && a >= c && c >= b)
      cout << b << c << a;
    else if (b >= a && b >= c && a >= c)
      cout << c << a << b;
    else if (b >= a && b >= c && c >= a)
      cout << a << c << b;
    else if (c >= b && c >= a && a >= b)
      cout << b << a << c;
    else if (c >= b && c >= a && b >= a)
      cout << a << b << c;      
  }
  return 0;
}
