You are given \(Q\) queries of the form:
a b\((-10^9 \le a,b \le 10^9)\). This query asks for \(a-b\) if \(a < b\), and \(b-a\) if \(b \le a\).
For each query, print out the desired answer!
The first line will contain the integer \(Q\ (1 \le Q \le 10^5)\).
The next \(Q\) lines will each contain a query of the form defined above.
For each query, print the desired answer on its own line.
