Search In a Big Sorted ArrayGiven a big sorted array with positive integers sorted by ascending order. The array is so big so that you can not get the length of the whole array directly, and you can only access the kth number by ArrayReader.get(k) (or ArrayReader->get(k) for C++)...

Rust | Array Example: Write a program to search an item into the array using binary search. Submitted byNidhi, on October 21, 2021 Problem Solution: In this program, we will create an array of integer elements then we will read an item from the user and search the item into the array...
Binary search is the most commonly used techniques, it work only on sorted array. Answer and Explanation: Binary Search is only guaranteed to work properly if the array being searched is sorted. Answer: The statement is true. Binary search provide...
Creating A Binary Search Tree (BST) Given an array of elements, we need to construct a BST. Let’s do this as shown below: Given array:45, 10, 7, 90, 12, 50, 13, 39, 57 Let’s first consider the top element i.e. 45 as the root node. From here we will go on creating th...
For example, if you start with an empty binary search tree and insert nodes in increasing key order, the unique path for each one will always be the rightmost path. Each insertion adds one more node at the bottom right. If you reverse the order of the nodes and insert them into an emp...
