Problem Statement

Write a C program to compute and print the prefix sum array of a given 1D array.

Input Format

First line: N. Second line: N space-separated integers.

Output Format

Print the prefix sum array separated by a space.

Constraints

1 <= N <= 1000

Sample Input

5
1 2 3 4 5

Sample Output

1 3 6 10 15

Explanation

Prefix sums: [1, 1+2=3, 1+2+3=6, 1+2+3+4=10, 1+2+3+4+5=15].

Starter Code

#include <stdio.h>

int main() {

    if (scanf("%d", &n) == 1) {
        int arr[n];
        for (int i = 0; i < n; i++) scanf("%d", &arr[i]);
        // Write your code here
    }
    return 0;
