Q2. Swap the bits in a byte.
Ans. 
Swapping bits in a byte involves exchanging the positions of bits within an 8-bit binary number.
• A byte consists of 8 bits, indexed from 0 to 7.

• Example: For byte 10110010, swapping gives 01011001.

• Use bitwise operations: AND, OR, and XOR to manipulate bits efficiently.

• In programming, you can use masks to isolate and swap bits.
