Given an Integer number convert into Binary Number using arrays as a stack.
Example:
Input : 10 Output: 1010 Input : 16 Output: 10000
Approach:
- Divide the number by 2 and store the remainder of the number in the array.
- Divide the number by 2.
- Repeat the process until the number becomes zero.
- Print the array in reverse order.
