DESCRIPTION
Two octal number integers a, b are given, and you need calculate the result a - b in octal notation.
If the result is negative, you should use the negative sign instead of complement notation.
INPUT
The first line is an integer T(1 <= T <= 1000), indicating the number of test cases.For each case, the first and only line contains two octal integers a, b.(0 <= a, b < 2^32)
OUTPUT
Print the result, one per line, in octal notation.

if(a>=b)
