Problem Statement

Write a C program to find the median of an unsorted array of integers. If N is odd, print the middle element as float rounded to 2 decimal places. If N is even, print the average of the two middle elements.

Input Format

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

Output Format

Print the median formatted to 2 decimal places.

Constraints

1 <= N <= 1000

Sample Input

5
1 3 4 2 7

Sample Output

3.00

Explanation

Sorted array is [1, 2, 3, 4, 7]. The median is the middle element 3.00.

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;
}
