Sliding Window Sum

Code

#include <stdio.h>

void sliding_window_sum(int arr[], int n, int k) {
    // Your logic here
    int tmp=0;
    int temp[n]={0};
    int cnt=0;

    int sum=0;
    
    for (int i=0;i<k;i++){
         sum+=arr[i];

    }

    temp[cnt++]=sum;
    printf("%d ",temp[cnt-1]);

    for (int i=k;i<n;i++){

          
           
           sum=sum-arr[i-k]+arr[i];
           temp[cnt++]=sum;
           printf("%d ",temp[cnt-1]);
    }
    
   
        
    }


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;
}
