Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    for(int i=0;i<=n-k;i++) // taking window size to loop through
    {
        int sum = 0;
        for(int j=i;j<i+k;j++)
        {
            sum += arr[j];
        }
        printf("%d", sum);
        
        if(i < n-k)
        {
            printf(" ");
        }
    }

}

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;
}
