Problem Statement The problem “Mean of range in array” states that you are given an integer array and q number of queries. Each query contains the left and right as a range. The problem statement asks to find out the floor mean value of all the integers that come in …
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 …
Problem Statement Suppose you have an integer array. The problem “Replace two consecutive equal values with one greater” asks to replace all those pair values say ‘a’ which comes consecutively with a number “a+1” 1 greater than them (two consecutive numbers), such that even after the modification or repetition there …
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 “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 “Subarrays with distinct elements” states that you are given an array of integer elements. The problem statement asks to find the sum of lengths of contiguous sub-arrays that are having all elements different from each other. Example arr[] = {3, 1, 2, 1} 4 Explanation: The sub-arrays are …
In this article, we will learn the insertion in a binary tree. We have already seen the concept of BFS in the previous article, so here we will use the same concept to insert the data in a binary tree. The concept is traversing the tree in level order and …
Problem Statement In the “Check if all Rows of a Matrix are Circular Rotations of Each Other” problem we have given a char matrix, write a program to find whether all rows are circular rotations of each other or not. If all rows are circular rotations of each other print …
Problem Statement Given two input strings, a pattern and a string. We need to sort the string according to the order defined by the pattern. Pattern string has no duplicates and it has all characters of the string. Input Format The first line containing a string s which we need …
Problem Statement In the “Convert a String that is Repetition of a Substring of Length K” problem we have given a string “s” and an integer “k”. Write a program to check whether is it possible to convert it to a string that is the repetition of a substring with …
