When you enter 8 numbers from 0 to 9, write a program that outputs the difference between the largest integer and the smallest integer that can sort the 8 numbers. The number that can be sorted may start from 0, such as 00135569.



Input

Given multiple datasets. The number of datasets n (n ≤ 50) is given on the first line. Then n rows of data are given. Each data is a sequence of 8 numbers (0 to 9 numbers).

Output

For each dataset, output the difference between the largest and smallest integers that can be rearranged in the entered numbers on one line.

Example

Input

2
65539010
65539010


Output

96417531
96417531
N = int(input())

for l in range(N):
    s = input()
    n = []
    for i in range(len(s)):
        n.append(int(s[i]))
    a,b = 0,0
    n.sort()
    for i in range(len(n)):
        a *= 10
        a += n[i]

        b *= 10
        b += n[len(n)-i-1]
    print(b-a)
