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
if __name__ == '__main__':

	n = int(input())

	for i in range(n):
		tmp = ""
		tmp2 = ""
		line = list(map(int,input()))
		ans = sorted(line)
		for j in ans:
			tmp += str(j)

		ans2 = sorted(ans,reverse=True)
		for k in ans2:
			tmp2 += str(k)

		print(int(tmp2) - int(tmp))
