The challenge

Numbers ending with zeros are boring.

They might be fun in your world, but not here.

Get rid of them. Only the ending ones.

1450 -> 145
960000 -> 96
1050 -> 105
-1050 -> -105

The solution in Python code

Option 1:

def no_boring_zeros(n):
    n = str(n)
    for i in range(len(n)-1, 0, -1):
        if n[i]=="0":
            n = n[:-1:]
        else:
            return int(n)
    return int(n)

Option 2:

def no_boring_zeros(n):
    try:
        return int(str(n).rstrip('0'))
    except ValueError:
        return 0

Option 3:

def no_boring_zeros(n):
  return int(str(n).rstrip("0")) if n else n
