Q2. How to find a particular element in a sorted array?
Ans. 
Use binary search to efficiently find a particular element in a sorted array.
• Start by comparing the target element with the middle element of the array.

• If the target element is less than the middle element, search the left half of the array.

• If the target element is greater than the middle element, search the right half of the array.

• Repeat the process until the target element is found or the search space is empty.
