Day 10: Binary Numbers

    I started off using the built-in bin() function, but it felt like the point was to do it myself, so I made user_bin to replicate it.

    #!/bin/python3

import math
import os
import random
import re
import sys

def user_bin(n):
    n = int(n)
    out = ""
    while(n > 0):
        remainder = n % 2
        n = n//2
        out += str(remainder)
    return out[::-1]

if __name__ == '__main__':
    n = int(input().strip())
    print(max([len(i) for i in user_bin(n).split("0")]))
