Problem Description

HazelFan is given two positive integers a,b， and he wants to calculate amodb. But now he forgets the value of b and only remember the value of a, please tell him the number of different possible results.

 

Input

The first line contains a positive integer T(1≤T≤5), denoting the number of test cases.
For each test case:
A single line contains a positive integer a(1≤a≤109).

 

Output

For each test case:
A single line contains a nonnegative integer, denoting the answer.

 

Sample Input

2
1
3

 

Sample Output

2

3

找规律:  ans=(n+1)/2+1

吐血，看了一个小时，完全搞错mod的含义了

#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;
typedef long long int ll;

int main()
{
	int t;
	ll n;
	scanf("%d",&t);
	while(t--)
	{
		scanf("%lld",&n);
		printf("%lld\n",(n+1)/2+1);
	}
	return 0;
}
