Last Updated: 7 Jan, 2021
Difficulty: Easy


Try Problem

You are given an array “ARR” of size N. Your task is to find out the sum of maximum and minimum elements in the array.

Follow Up:
Can you do the above task in a minimum number of comparisons?
Input format:
The first line of input contains a single integer T, representing the number of test cases.
Then the T test cases follow. 

The first line of each test case contains a single integer N representing the size of the array 'ARR'.

The second line of each test case contains N space separated integers representing the elements of the array “arr”.
Output format:
For each test case, print the sum of the maximum and minimum element of the array 'ARR'.
You do not need to print anything. It has already been taken care of. Just implement the given function.
1 <= T <= 10
1 <= N <= 10^5 
-10^9 <= ARR[i] <= 10^9

Time limit: 1 second

Approach 1

Sort the array so that the 0th element will be the minimum value of the array and the last element will be the maximum value present in out array.
