Search in Rotated Sorted Array | Binary Search | Animated DSA Explanation in Java

Search in Rotated Sorted Array (Medium) explained step by step with animations: the idea, a brute force, the optimal solution and its complexity, with Java code. A sorted array of distinct integers was rotated at an unknown pivot. Given a target, return its index or -1, in O(log n) time. Java code + notes: https://algorung.com/dsa/binary-searc...
