What if you could solve certain problems faster than normal arithmetic operations?

That’s the power of Bit Manipulation — one of the most underrated but extremely powerful techniques in programming and coding interviews.

In today’s lecture, I explained the fundamentals of Bit Manipulation and demonstrated how bitwise operations work in Java. Then we solved an important practical problem: checking whether a number is even or odd without using the modulo operator, using only bit manipulation.

This concept is widely used in low-level programming, performance optimization, and coding interviews.

WHAT YOU WILL LEARN IN THIS VIDEO
* What Bit Manipulation really means
* Why Bit Manipulation is important in programming
* Understanding binary representation of numbers
* Important Bitwise Operators in Java:
AND (&), OR (|), NOT (~), XOR (^), Left Shift, Right Shift
* Practical problem solved from scratch:
Check if a number is Even or Odd without using the % operator
* Understanding how the least significant bit (LSB) determines parity
* Writing and running the Java implementation
* Verifying output step by step

INTERVIEW INTELLIGENCE
Bit Manipulation frequently appears in coding interviews because it tests low-level understanding of numbers and efficiency.
Common interview problems include:
* Check Even/Odd using bits
* Power of Two check
* Counting set bits
* Single number problem (XOR trick)
* Swapping numbers using XOR

Understanding these basics builds the foundation for advanced bit manipulation problems.

WHY THIS VIDEO IS IMPORTANT
Many developers ignore bit manipulation because it looks confusing at first.
But once you understand it, you can:
Write faster algorithms
Optimize space and time complexity
Solve tricky interview problems easily

This lecture makes the topic simple and practical.
