Search in Rotated Sorted Array Pattern 1 | Lecture-46 | Java & DSA Foundation course
In this video, we will be discussing how to use binary search to solve problems on a rotated sorted array in Java. A rotated sorted array is a type of array where the elements are sorted in ascending order but the array has been rotated by some unknown pivot. This can make finding elements in the array much more challenging. However, with the help of binary search, we can still achieve an efficient solution. In this lecture manvi maam will cover various problems that can be solved using binary search on a rotated sorted array and provide step-by-step implementation in Java. Happy learning. See you all in the lecture.
