My issue

It is showing that 1 is correct 1 is WA,
I created a separate vector consisting of the song with same language and then sorted it and reversed it to find the maximum length of the playlist:
until k is reached!

My code

#include <bits/stdc++.h>
#include <algorithm>
using namespace std;
void solve()
{
    int n, k, l;
    cin >> n >> k >> l;
    int m[n], L[n];
    for (int i = 0; i < n; i++)
    {
        cin >> m[i] >> L[i];
    }
    vector<int> len;
    int size{0};
    for (int i = 0; i < n; i++)
    {
        if (L[i] == l)
        {
            len.push_back(m[i]);
            size++;
        }
    }
    if (size != 0)
    {
        int max_length = 0;
        int term = 0;
        sort(len.begin(), len.end());
        for (int i = len.size() - 1; i >= 0; i--)
        {
            term++;
            if (term > k)
            {
                break;
            }
            else
            {
                max_length += len.at(i);
            }
        }
        cout << max_length << endl;
    }else if(size==0){
        cout<<"-1"<<endl;
    }
}
int main()
{
    int n;
    cin >> n;
    while (n--)
    {
        solve();
    }
}

i got the same problem with python

from functools import reduce

# Read the number of test cases
for _ in range(int(input())):
    n, k, l = map(int, input().split())
    values = set()
    # Read and filter values
    for _ in range(n):
        a, b = map(int, input().split())
        if b == l:
            values.add(a)

    # Sort the unique values
    sorted_values = sorted(values, reverse=True)
    q=len(sorted_values)
    for i in range(q-1):
        if sorted_values[i] == sorted_values[i+1]:
            sorted_values.remove(sorted_values[i])
    if len(sorted_values) == 0 or len(sorted_values) == k or k>len(sorted_values):
        print(-1)
    elif len(sorted_values) == k:
        print(sum(sorted_values))
    elif len(sorted_values)==2:
        print(max(sorted_values))
    elif k<len(sorted_values):
        for i in range(k):
            sorted_values.pop()
        sum=0
        for i in range(k):
            sum+=sorted_values[i]
        print(sum)
