For example: the position of the first store 1, store the second position is 3, the distance is 3-1 = 2

Input

A first line of input integer T, representative of the next set of test data with a T

Next T lines, each of the two numbers a and B input, respectively represent the location of the two stores

1 £ T £ 10000,1 £ n, m £ 10000

Output

For each set of test data corresponding to the output answer
