Solution: Find the Floor and Ceil of a Number
Explore how to apply a modified binary search algorithm to determine the floor and ceil of a target number in a sorted array. This lesson guides you through step-by-step code explanations that illustrate how to update search boundaries and maintain efficient searching to achieve a time complexity of O(log n).

Solution
We can make use of the fact that the array is sorted. So, by a little modification of the binary search algorithm, we can successfully crack this problem. The core idea remains the same: we divide the array at ...
