Sliding Window Sum

Code

#include <stdio.h>

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

    int sum=0;
    bool b= false;

    for(int i=0;i<n;i++){ 

        for(int j=i;j<i+k;j++){ 
            
            sum=sum+arr[j];
            if(arr[n-1] == arr[j]){
                b=true;
                break;
            }

        }

        printf("%d ",sum);
        if(b==true){
            break;
        }
        sum=0;
    }

}

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;
}
