One steps through integer points of the straight line. The length of a step must be nonnegative and can be by one bigger than, equal to, or by one smaller than the length of the previous step. What is the minimum number of steps in order to get from x to y? The length of the first and the last step must be 1.
Input:
Input consists of a line containing n, the number of test cases.
Output:
For each test case, a line follows with two integers: 0 <= x <= y < 2^31. For each test case, print a line giving the minimum number of steps to get from x to y.
Example Input:
3
45 48
45 49
45 50

有n组数据，每组问你从x到y最少需要多少步，第一步和最后一步必须是1，每步不能是负的。
