Sliding Window Sum

Code

#include <stdio.h>

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


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

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;
}

Solving Approach

create a sum function , that calculates the array sum and prints, now pass each subarray to this function .
