Convert Octal To Binary

Write a program to convert octal to binary

Octal is a base-8 number system. It uses only eight digits: 0, 1, 2, 3, 4, 5, 6, and 7. The digits are called octits. An octit is the smallest unit of information in a computer. An octit can be used to represent a single value, such as 0, 1, 2, 3, 4, 5, 6, or 7, or it can be used to represent a single state, such as on or off.

Binary is a base-2 number system. It uses only two digits: 0 and 1. The digits are called bits. A bit is the smallest unit of information in a computer. A bit can be either 0 or 1. A bit can be used to represent a single value, such as 0 or 1, or it can be used to represent a single state, such as on or off.

To convert an octal number to binary, we can use the following algorithm:

1. Convert the octal number to decimal.
2. Convert the decimal number to binary.

Input  : 12
Output : 1010
