Consecutive 0s and 1s Binary Pattern

The program must accept an integer N as the input. The program must find the binary representation of N and print the desired pattern as shown in the Example Input/Output section

Boundary Condition(s):
1 <= N <= 10^17

Input Format:
The first line contains N

Output Format:
The lines containing the desired pattern as shown in the Example Input/Output section

Example Input/Output 1:
Input
463
Output:
111
00
1111
Explanation:
The binary representation of 463 is 111001111

Example Input/Output 2:
Input
81
Output
1
0
1
000
1
Explanation:
The binary representation of 81 is 1010001.
