Bit manipulation involves operations on individual bits within a binary representation of numbers.

I. TIPS & STRATEGIES FOR SOLVING BIT MANIPULATION PROBLEMS:

1. Understand Basic Bitwise Operations:

• Familiarize yourself with basic bitwise operations such as AND, OR, XOR, NOT, left shift, and right shift. Understand their properties and use cases.
• Bit manipulation involves the manipulation of individual bits in a binary representation of data.
• Bit manipulation is often used in scenarios where memory and processing power are critical, and it’s a fundamental concept in computer science and embedded systems.

1.1 Indicator of Bitwise Operations:
