Chef is given 3 integers A, B, and C such that A < B < C.

Chef needs to find the value of max(A, B, C) - min(A, B, C).

Here max(A, B, C) denotes the maximum value among A, B, C while min(A, B, C) denotes the minimum value among A, B, C.

------ Input Format ------

• The first line of input will contain a single integer T, denoting the number of test cases.
• Each test case consists of 3 integers A, B, C.

------ Output Format ------

For each test case, output the value of max(A, B, C) - min(A, B, C).

------ Constraints ------

$1 ≤ T ≤ 10$
$1 ≤ A < B < C ≤ 10$

----- Sample Input 1 ------
4
1 3 10
5 6 7
3 8 9
2 5 6

----- Sample Output 1 ------
9
2
6
4

----- explanation 1 ------
Test case $1$: Here, $max(1, 3, 10) = 10$ and $min(1, 3, 10) = 1$. Thus, the difference is $9$.

Test case $2$: Here, $max(5, 6, 7) = 7$ and $min(5, 6, 7) = 5$. Thus, the difference is $2$.

Test case $3$: Here, $max(3, 8, 9) = 9$ and $min(3, 8, 9) = 3$. Thus, the difference is $6$.

Test case $4$: Here, $max(2, 5, 6) = 6$ and $min(2, 5, 6) = 2$. Thus, the difference is $4$.
