B'You are given three points with integer coordinates x_1 , x_2 , and x_3 on the X axis ( 1 <= q x_i <= q 10 ). You can choose any point with an integer coordinate a on the X axis. Note that the point a may coincide with x_1 , x_2 , or x_3 . Let f(a) be the total distance from the given points to the point a . Find the smallest value of f(a) . The distance between points a and b is equal to |a - b| . For example, the distance between points a = 5 and b = 2 is 3 . Each test consists of multiple test cases. The first line contains a single integer t ( 1 <= q t <= q 10^3 ) -- the number of test cases. Then follows their descriptions. The single line of each test case contains three integers x_1 , x_2 , and x_3 ( 1 <= q x_i <= q 10 ) -- the coordinates of the points. For each test case, output the smallest value of f(a) . In the first test case, the smallest value of f(a) is achieved when a = 1 : f(1) = |1 - 1| + |1 - 1| + |1 - 1| = 0 . In the second test case, the smallest value of f(a) is achieved when a = 5 : f(5) = |1 - 5| + |5 - 5| + |9 - 5| = 8 . In the third test case, the smallest value of f(a) is achieved when a = 8 : f(8) = |8 - 8| + |2 - 8| + |8 - 8| = 6 . In the fourth test case, the smallest value of f(a) is achieved when a = 9 : f(10) = |10 - 9| + |9 - 9| + |3 - 9| = 7 . '...
