B'Vladislav has n cards numbered 1, 2, ... , n . He wants to lay them down in a row as follows: The first line contains an integer t ( 1 <= q t <= q 5 cdot 10^4 ) -- the number of test cases. The only line of each test case contains two integers n and k ( 1 <= q k <= q n <= q 10^9 ) -- the number of cards Vlad has, and the position of the card you need to output. For each test case, output a single integer -- the k -th card Vladislav lays down. In the first seven test cases, n=7 . Vladislav lays down the cards as follows: '...
