Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. The first line of each test case contains 4 space separated integer points b , c , d

Output:
For each test case print 1 if the four points form a square else print 0.
Remember to output the answer of each test case in a new line.

Constraints:
1 <= T <= 200
1 <= a,b,c,d <= 100

Example:
Input
:
2
