Problem :- Given the marks of all students, calculate the mean.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of two lines. The first line of each test case consists of an integer N denoting the number of students. The second line of each test case consists of N space separated integers denoting the marks of all the students.

Output:
Corresponding to each test case, print the floor value of the mean in a new line.

Solution :-

#include <bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t--)
{
long long int n,i,mean=0,res=0;
cin>>n;
int arr[n];

for(i=0;i<n;i++)
cin>>arr[i];

for(i=0;i<n;i++)
{
res+=arr[i];
}
mean=res/n;
cout<<mean<<endl;

}
return 0;

}

Output :-
