Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here

    int NumE = (n-k) +1;

    int NumArr[NumE] = {0};

    for (int i = 0; i<NumE; i++){
        for (int j = 0; j<k; j++){
            NumArr[i] = NumArr[i]+arr[i+j];
        }
    }

    for (int q = 0; q < NumE; q++){
        printf("%d ", NumArr[q]);
    }
}

int main() {
    int n, k, arr[100];
    scanf("%d %d", &n, &k);
    for (int i = 0; i < n; i++) scanf("%d", &arr[i]);

    sliding_window_sum(arr, n, k);
    return 0;
}
