Given four integers a,b,m,n . Find whether pow(a,b) is greater than pow(m,n) or not. Where pow(x,y) denotes x raised to the power y.
First line of input contains of an integer 'T 'denoting number of test cases .Only line of each testcase contains four integers a,b,m and n.
For each case in a new line print 1 if pow(a,b) is greater , print 0 if pow(m,n) is greater else print -1 if both are equal.
1 <= T <= 1000
0 <= b,n <= 1018
1 <= a,m <= 1018
