把for循环改了
我的AC代码：
```
#include <cstdio>
#include <cstring>
#include <algorithm>
using namespace std;
const int maxn = 1e2 + 10;
bool flag;
int n, cnt, a[maxn];
int main() {
scanf("%d", &n);
for (int i = 1; i <= n; i++) scanf("%d", a + i);
sort(a + 1, a + n + 1);
for (int i = 1; i <= n; i++) {
flag = false;
for (int j = 1; j <= i; j++) {
for (int k = 1; k <= i; k++) {
if (j - k && a[j] <= a[k] && a[j] + a[k] == a[i]) {
flag = true;
break;
}
}
if (flag) break;
}
cnt += flag;
}
printf("%d\n", cnt);
return 0;
}
```
