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

213

 

Sample Output

23

这场比赛里最简单的题目 我以为是数论 就扔给了队友 结果队友wr了两次 后来一看就是一道简单的思维题 忍不住很很的吐槽一波队友O__O "…

ac代码：

#include<cstdio>#include<iostream>using namespace std;int main(){    int t;    cin>>t;    int n;    while(t--)    {        scanf("%d",&n);        if(n==1)            cout<<2<<endl;        if(n==2)            cout<<3<<endl;        if(n!=1&&n!=2)        {            if(n&1)            {                cout<<(n+1)/2+1<<endl;            }            else            {                cout<<n/2+1<<endl;            }        }    }    return 0;}
