一个简单分段求和的问题
示例通过了但又数据没通过
想问问有没有解决办法
感谢

#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
    int T;
    cin >> T;
    for (; T > 0; T--) {
        int N, M, a[100000] = { '\0' }, n = 0, sum = 0;
        char c[100000];
        cin >> N >> M;
        c[0] = getchar();
        c[0] = getchar();
        char std = c[0];
        for (int i = 1; i < N; i++) {
            c[i] = getchar();
            if (std == c[i]) a[n]++;
            else {
                n++;
                std = c[i];
            }
        }
        for (int i = 0; i <= n; i++)
            a[i]++;
        sort(a, a + n + 1);
        for (int i = M; i > 0; i--) {
            sum += a[n - M + i];
        }
        cout << sum << endl;
    }
    return 0;
}

#include<iostream>
#include<string>
using namespace std;

int main(){
    int T;
    cin >> T;
    while (T--){
        int n, m;
        cin >> n >> m;
        string portals;
        cin >> portals;
        // Your code here
        int result = 0;
        // Your code here
        cout << result << endl;
    }
    return 0;
}
