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 这个题比较水,用了map还是不如线性递推快,但是线性递推就超时了,于是打表找规律,然后发现规律如下。
于是可写出代码:
#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
const ll mod = 1e9 + 7;
int main()
{
int t,n;
scanf("%d",&t);
while(t--)
{
scanf("%d",&n);
if(n&1)
printf("%d\n",n/2+2);
else
printf("%d\n",n/2+1);
}
return 0;
}
