Write a menu driven program using a method Number() to perform the following tasks:

1. Accept a number from the user and display it in its Binary Equivalents.
   For example:
   Sample Input: (21)₁₀
   Sample Output: (10101)₂
2. Accept a binary number from the user and display it in its Decimal Equivalents.
   For example:
   Sample Input: (11101)₂
   Sample Output: (29)₁₀
