Q1. Why ZS, swap two numbers without using extra variable
Ans. 
To swap two numbers without using an extra variable, you can use arithmetic operations like addition and subtraction.
• Store the sum of the two numbers in one of the variables, then subtract one number from the sum to get the other number.

• For example, to swap numbers a=5 and b=10: a = a + b; b = a - b; a = a - b; Now a=10 and b=5.
