Please, tell me why is it still wrong?

#1 
#include <iostream>

int main() {
    int N = 0, t = 0, curr_sum = 0, max_sum = 0, A[20] = {0},
        maxSum[100000] = {0};
    std::cin >> N;
    for (int i = 0; i < N; ++i) {
        std::cin >> t;
        for (int j = 0; j < t; ++j) {
            std::cin >> A[j];
            curr_sum += A[j];
            if (curr_sum < 0) curr_sum = 0;
            max_sum = std::max(max_sum, curr_sum);
        }
        maxSum[i] = max_sum;
    }
    for (int i = 0; i < N; ++i) std::cout << maxSum[i] << '\n';
    return 0;
}
