So, in the worst case, **binary** **search** will take log n comparisons and so, the time taken also in the worst case is proportional to log in or in other words, it is big O of log n in terms of time complexity and big O of log n is a lot lot lot more efficient than o n algorithm.

Find the number of rotations in a circularly sorted array Easy. **Search** an element in a circularly sorted array Medium. Find the first or last occurrence of a given number in a sorted array Easy. As one novel meta-heuristic algorithm, African Vultures Optimization Algorithm (AVOA) has been proved to be efficient in solving continuous optimization **problems**. However, many real-world optimization **problems** are in the discrete form, and the continuous characteristics of AVOA make it unsuitable for solving discrete optimization **problems**.

When you **search** for such an element, you might be asking one of the following questions: The answer to the first question tells you whether an element is present in the collection.

**Binary** **Search** Explanation & Related **Problems**-Java. Suppose we want to **search** for a particular element in an array of 'n' elements and return its index if it exists or return -1 if it doesn't exist.

**Binary** **Search** Tree : Lowest Common Ancestor. You are given pointer to the root of the **binary** **search** tree and two values v1 and v2. You need to return the lowest common ancestor (LCA) of v1 and v2 in the **binary** **search** tree. In the diagram above, the lowest common ancestor of the nodes 4 and 6 is the node 3. Web. Web. One of the best reference for the tricky point of **binary** **search** is Jon Bentley's Programming Pearls. The whole chapter 4 addresses this **problem**, which shows many wrong versions of **binary** **search**. e.g. you want to find the first number that is greater than or equal to your query x.

So, in the worst case, **binary** **search** will take log n comparisons and so, the time taken also in the worst case is proportional to log in or in other words, it is big O of log n in terms of time complexity and big O of log n is a lot lot lot more efficient than o n algorithm.
