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 i in range(n):
    Max_num = ""
    Min_num = ""
    n = str(input())
    Lis = list(map(str,n))
    Min_num_lis = sorted(Lis)
    Max_num_lis = sorted(Lis)[::-1]
    for j in range(8):
        Max_num = Max_num + Max_num_lis[j]
        Min_num = Min_num + Min_num_lis[j]
    sa = int(Max_num) - int(Min_num)
    print(sa)
