Hackerrank Day 10: Binary Numbers

Task
Given a base- integer, , convert it to binary (base-). Then find and print the base- integer denoting the maximum number of consecutive 's in 's binary representation.

Sample Case 1:
The binary representation of 5 is 101 , so the maximum number of consecutive 1's is 1 .

Sample Case 2:
The binary representation of 13  is 1101 , so the maximum number of consecutive 1's is 2 .

def ten_to_two(n):

        data.append(n%2)
        n=n//2
    return data

def count(data):
    d={}
    d[0]=data[0] #用字典来记录连续1的个数
    for i in range(1,len(data)):
        d[i]=data[i] #最先,让等于1的元素计数为1
        if data[i-1]==data[i]==1:  #如果前面的元素和本元素相等且等于1,就计数=前一元素的计数+1
            d[i]=d[i-1]+1
    return max(d.values())

if __name__ == '__main__':
    n = int(input())
    data=[]
    data=ten_to_two(n)
    result=count(data)
    print(int(result))
