Largest Element in ArrayLargest Element in Array

Given an array, find the largest element in it.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains an integer n , the no of elements in the array. Then next line contains n integers of the array.

Output:
Print the maximum element in the array.

Constraints:
1<=T<=100
1<=n<=100
1<=a[i]<=1000

Example:
Input:
2
5
10 324 45 90 9808
7
1 2 0 3 2 4 5

Output :
9808
5

Your code

#include<iostream>

using namespace std;

int main()

{

int t;

cin>>t;

while(t--)

{

int n;

cin>>n;

int a[100],i;

int ans=-1;

for(i=0; i<n; i++)

{

cin>>a[i];

ans=max(ans,a[i]);

}

cout<<ans<<endl;

}

}
