Q1. Gave one problem of binary search?
Ans. 
Binary search is a technique used to efficiently locate a target value within a sorted array.
• Start by comparing the target value to the middle element of the array.

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

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

• Repeat the process until the target value is found or the subarray is empty.
