You are given three digits a�, b�, c�. Two of them are equal, but the third one is different from the other two.
Find the value that occurs exactly once.
Input
The first line contains a single integer t� (1≤t≤2701≤�≤270) — the number of test cases.
The only line of each test case contains three digits a�, b�, c� (0≤a0≤�, b�, c≤9�≤9). Two of the digits are equal, but the third one is different from the other two.
Output
For each test case, output the value that occurs exactly once.

解题说明：三个数中两个数一样，找出另一个数，水题，直接比较即可。
#include<stdio.h>
int main(void)
{
int t, a, b, c;
scanf("%d", &t);
while (t--)
{
scanf("%d%d%d", &a, &b, &c);
printf("%d\n", a == b ? c : a == c ? b : a);
}
return 0;
}
