Problem Statement

Write a C program to find a peak element in an array (an element that is greater than or equal to its neighbors). Print its index.

Input Format

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

Output Format

Print the index of any valid peak element.

Constraints

1 <= N <= 1000

Sample Input

4
1 2 3 1

Sample Output

Explanation

Element at index 2 is 3, which is greater than its neighbors 2 and 1.

Starter Code

#include <stdio.h>

int main() {
    int n;
    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;
}
