You even tried to help me a lot.

Thanks

#include <bits/stdc++.h>
using namespace std;
void f()
{
    int n;
    cin >> n;
    int x;
    cin >> x;
    string A, B;
    cin >> A >> B;
    int cnt = 0;
    for (int i = 0; i < n; i++)
    {
        if (A[i] != B[i])
            cnt++;
    }
    if (cnt & 1)
    {
        cout << -1 << '\n';
        return;
    }
    int cost = 0;
    vector<int> a;
    for (int i = 0; i < n; i++)
    {
        if (A[i] != B[i])
            a.push_back(i);
    }
    int k = a.size();
    for (int i = 0; i < k / 2 - 1; i++)
    {
        cost += min(x, a[2 * i + 1] - a[2 * i]);
        cost += min(k, a[k] - a[1]);
    }
    cout << cost << '\n';
}

signed main()
{
    int t = 1;
    cin >> t;
    while (t--)
        f();
}

What is wrong here, can you pls help me to fix

n = 6 , K = 2 A = 101011 B = 010010

Output: 3

n = 4, k = 3 A = 1010 B = 0001

Output: -1

getting wrong :)

me too, how to buy this, please anyone

wow bro, such a great job. Thanks

OK.

But what is this bro

i don't think so

he's earning more than 2,00,000 per month, by mentoring.

just by making others fool through linkedIn.

another cheater

just look at the cheating technique, some useless loops after each and every line,,

according to his graph, looks like genuine

but although a cheater
