Problem Description
Solving problem is a interesting thing. Yifenfei like to slove different problem,because he think it is a way let him more intelligent. But as we know,yifenfei is weak in math. When he come up against a difficult math problem, he always try to get a hand. Now the problem is coming! Let we
define T(n) as the sum of all numbers which are positive integers can divied n. and S(n) = T(1) + T(2) + T(3)…..+T(n). 
 

Input
The first line of the input contains an integer T which means the number of test cases. Then T lines follow, each line consists of only one positive integers n. You may assume the integer will not exceed 2^31.
 

Output
For each test case, you should output one lines of one integer S(n) %2. So you may see the answer is always 0 or 1 .
 

Sample Input
3 1 2 3
 

Sample Output
1 0 0
Hint
Hint S(3) = T(1) + T(2) +T(3) = 1 + (1+2) + (1+3) = 8 S(3) % 2 = 0

都能在网上找到规律就是:凡是“能够被完全开方”或者“被2整除后能够完全被开方”的数,它的(T(N) % 2)都是1。
从此我的博客里面多了一个规律的分组。
//15MS	228K
#include<stdio.h>
#include<math.h>
int main()
{
    int t;
    scanf("%d",&t);
    while(t--)
    {
        int n,count=0;
        scanf("%d",&n);
        for(int i=1;i<=n;i++)
        {
            if(i*i*2<=n)count++;
            if(i*i<=n)count++;
            else break;
        }
        printf("%d\n",count%2);
    }
    return 0;
}
