What is the data in the test 19?

what is answer for that test
5 -9
4 -8 -6 1 -10
?

Can you suggest what is causing this error.

N = int(input())
s = [0]

for i in range(N):
   k = int(input())
   s.append(int(s[i] + k))

Q = int(input())
while Q:
   l, r = map(int, input().split())
   print(s[r] - s[l-1])
   Q -= 1

#include <iostream>
using namespace std;

int main() {
    int n, k, *arr,raz,y=0,ost=0;
    cin >> n >> k;
    arr = new int[n];
    for (int i = 0; i < n; i++) {
        cin >> arr[i];
    }
    for (int i = 0; i < n; i++) {
        raz = 5 - arr[i];
        if (raz >= 0) {
            y = y + raz;
        }
        else {
            y = y;
            ost = ost + raz * -1;
        }
    }

    cout << ost << " " << y;
    return 0;
}

ans: 1 1 2 3

On the first sight i thought i'd need O(3 ^ 16) but the problem is much easier.

if you WA on #3 ,please use unsigned __int64 and high-accuracy
if you WA on #9 ,try this

2
10
3

The answer is 0

Edited by author 03.03.2022 10:56

cnt = 0
a = int(input())
a1 = list(map(int, input().split()))
b = int(input())
b1 = list(map(int, input().split()))
c = int(input())
c1 = list(map(int, input().split()))
for i in a1 :
    if i in b1 and c1 and a1 :
        cnt += 1
print(cnt)

what is wrong? tells "wrong answer"

Probably you're getting overflow
