Convert Decimal to Binary | Dataford Interview Questions

Take a decimal number in base 10, convert it to binary, interchange all the 1s and 0s, then convert that number back to base 10.

The input is a nonnegative decimal number represented as a string, with no leading zeros except for "0". Use the shortest binary representation, so leading zeroes are not included before interchange. Return the result as a decimal string.

Function: def invert_binary_decimal(decimal_string):

Constraints

1 <= len(decimal_string) <= 1000
decimal_string contains only characters from 0 through 9
decimal_string represents a nonnegative integer
decimal_string has no leading zeroes unless it is exactly "0"
The output must also be returned as a decimal string

Function Signature

def invert_binary_decimal(decimal_string):
