Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int mang[n-k+1];
    for(int i=0;i<=(n-k);i++){
        mang[i]=0;
        for(int f=0;f<k;f++){
            mang[i]=arr[i+f]+mang[i];
        }
    }
    for(int j=0;j<=(n-k);j++){
        printf("%d", mang[j]);
        if (j < (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;
}
