Input:
The first line of the input contains a single integer T, denoting the number of test cases. Then T test case follows. Each test case contains 2 lines:-
The number N
The power P

Output:
For each testcase, print 0 if the units digit changes, else print 1

Constraints:
1<=T<=100
1<=N<=1030
1<=P<=100

Example:

Input:
3
2
1
3
5
4
2

Output:
1
1
0

Explanation:
For testcase 1: 21=2 so units digit remains same. Therefore, we print 1
