Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int count = 0;
    for(int i=0;i<k;i++){
        count+=arr[i];
    }
    printf("%d ",count);
    for (int j=k;j<n;j++){
        count =count+arr[j]-arr[j-k];
        printf("%d ",count);
    }

}

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;
}
