if n == 0:
return 0
s = ''.join(sorted(str(n)))
c = s.count('0')
s = s.replace('0', '')
if s[0] != '-':
s = s[0] + '0' * c + s[1:]
else:
s = s[:2] + '0' * c + s[2:]
return int(s)
print(s)

Answer 1

Post the whole code.

Answer 2

Here is the whole code:

def min_permutation(n):
if n == 0:
return 0
s = ''.join(sorted(str(n)))
c = s.count('0')
s = s.replace('0', '')
if s[0] != '-':
s = s[0] + '0' * c + s[1:]
else:
s = s[:2] + '0' * c + s[2:]
return int(s)
print(s)

Answer 3

Given a number, find the permutation with the smallest absolute value (no leading zeros).

-20 => -20
-32 => -23
0 => 0
10 => 10
29394 => 23499
The input will always be an integer.
