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
def toValue(arr):
    s = 0
    l = len(arr) - 1
    i = 0
    while l >= 0:
        s += int(arr[i]) * pow(10,l)
        i += 1
        l -= 1
    return s
    
n = int(input())

for i in range(0,n):
    s = input()
    max = []
    for j in s:
        max.append(j)
    max = sorted(max,reverse=True)
    min = sorted(max)
    print(toValue(max) - toValue(min))
