Given a Binary Number B, find its decimal equivalent.
Example 1:
Input: B = 10001000
Output: 136
Example 2:
Input: B = 101100
Output: 44
Your Task:
You don't need to read or print anything. Your task is to complete the function binary_to_decimal() which takes the binary number as string input parameter and returns its decimal equivalent.
Expected Time Complexity: O(K * Log(K)) where K is number of bits in binary number. Expected Space Complexity: O(1)
Constraints:
1 <= number of bits in binary number <= 16

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
