ZOJ 3333 Guess the price

题目链接：http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=3758

题面：

In the television program "Shopping Street" of CCTV-2, two people, A and B are guessing price of a given item. You are asked to decide whose price is closer to the real price.

Input

There are multiple test cases. The first line of input is an integer T (T <= 10) indicating the number of test cases.

Each case contains three integers in one line: P, P_A, P_B (0 <= P_A, P_B <= P <= 100, P_A != P_B), indicating the real price, the price A guesses and the price B guesses.

Output

For each case, output "A" or "B" according to whose price is closer to the real price.

Sample Input

3
10 8 7
20 20 19
100 9 50

Sample Output

A
A
B

其实，题目有点纰漏，只说pa!=pb，但差值还是可能相等，不过测试样例里没有。

代码：

#include<iostream>
#include <cmath>
using namespace std;
int main()
{
	int t,p1,p2,p;
    cin>>t;
    while(t--)
    {
    	cin>>p>>p1>>p2;
    	if(abs(p-p1)<abs(p-p2))cout<<"A\n";
    	else cout<<"B\n";
    }
	return 0;
}
