Python Function Example: Bitwise Operations and Recursion

The code implements two functions:

• function_1: A simple function that adds two numbers together. This is included as a basic example and is not used in the main calculation.
• function_2: This function performs the main calculation. It takes two integers as input and performs the following operations:
  1. Bitwise AND: c = a & b calculates the bitwise AND of a and b.
  2. Bitwise XOR: d = a ^ b calculates the bitwise XOR of a and b.
  3. Conditional Recursion: If the result of the bitwise AND (c) is not 0, it performs a left shift on c (c = c << 1) and recursively calls function_2 with the shifted value of c and the result of the XOR operation (d). Otherwise, it returns the result of the XOR operation (d).

The code then prints the result of calling function_2 with the values 4 and 2, which outputs 6.

This code demonstrates the use of bitwise operations and recursion in Python functions. By understanding these concepts, you can create more complex and efficient algorithms.
