    if (n != m)
        return false;
 

    unordered_map<int, int> mp;

        mp[arr1[i]]++;
 

    for (int i = 0; i < n; i++) {
 

        if (mp.find(arr2[i]) == mp.end())
            return false;

        if (mp[arr2[i]] == 0)
            return false;

        mp[arr2[i]]--;
    }
    return true;
}
 

int main()
{
    int arr1[] = { 1, 2, 3, 4, 5 };
    int arr2[] = { 4, 3, 1, 5, 2 };
    int N = sizeof(arr1) / sizeof(int);
    int M = sizeof(arr2) / sizeof(int);
 

    if (checkArrays(arr1, arr2, N, M))
        cout << "Equal";
    else
        cout << "Not Equal";
    return 0;
