Problem Statement The problem “Products of ranges in an array” states that you are given an integer array consisting of numbers range from 1 to n and q number of queries. Each query contains the range. The problem statement asks to find out the product within the given range under …
Design a stack that supports getMin() in O(1) time and O(1) extra space. Thus the special stack data structure must support all the operations of the stack like – void push() int pop() bool isFull() bool isEmpty() in constant time. Add an additional operation getMin() to return the minimum value …
Problem Statement The problem “Iterative Method to find Height of Binary Tree” states that you are given a binary tree, find the height of the tree using the iterative method. Examples Input 3 Input 4 Algorithm for Iterative Method to find Height of Binary Tree The height of a tree …
Problem Statement The problem “Find the smallest binary digit multiple of given number” states that you are given a decimal number N. So find the smallest multiple of N that contains only the binary digits ‘0’ and ‘1’. Example 37 111 A detailed explanation can be found below in the …
Problem Statement “Find Minimum In Rotated Sorted Array” states that you are given a sorted array of size n which is rotated at some index. Find the minimum element in the array. Example a[ ] = {5, 1, 2, 3, 4} 1 Explanation: If we arrange the array in sorted …
Problem Statement “K’th Largest element in BST using constant extra space” states that you are given a binary search tree and you need to find the kth largest element in it. So if we arrange the elements of the binary search tree in descending order then we need to return …
Problem Statement “Elements to be added so that all elements of a range are present in array” states that you are given an array of integers. The problem statement asks to find out the count of elements to be added in an array so that all elements lie in the …
Problem Statement “A program to check if a binary tree is BST or not” states that you are given a binary tree and you need to check if the binary tree satisfies the properties of the binary search tree. So, the binary tree has the following properties: The left subtree …
Problem Statement “Maximum depth of binary tree” problem states that you are given a binary tree data structure. Print the maximum depth of the given binary tree. Example Input 2 Explanation: Maximum depth for the given tree is 2. Because there is only a single element below the root (i.e. …
Problem Statement “First missing positive” problem states that you are given an array a[ ] (sorted or unsorted) of size n. Find the first positive number that is missing in this array. Example a[ ] = {1, 3, -1, 8} 2 Explanation: If we sort the array we get {-1, …
