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())
nl = []
for i in range(n):
    a = int(input())
    b = list(str(a))
    c1 = list(sorted(b))
    c2 = list(reversed(c1))
    cc1 = ''
    cc2 = ''
    for i in range(len(c1)):
        cc1 = cc1 + c1[i]
        cc2 = cc2 + c2[i]
    c1n = int(cc1)
    c2n = int(cc2)
    nl.append(abs(c1n-c2n))
    
for i in range(len(nl)):
    print(nl[i])
