The problem “Count number of triplets with product equal to given number” states that we are given an integer array and a number m. The problem statement asks to find out the total number of triplets of with product equals to m. Example arr[] = {1,5,2,6,10,3} m=30 3 Explanation Triplets …
The problem “How to check if two given sets are disjoint?” states that suppose you are given two sets in the form of array say set1[] and set2[]. Your task is to find out whether the two sets are Disjoint Sets or not. Example inputSet1[] = {1, 15, 8, 9, …
Problem Statement The problem “Count Primes in Ranges” states that you are given a range [left, right], where 0<=left<=right<=10000. The problem statement asks to find out the total number of prime numbers within the range. Assuming that there will be a large number of queries. Example left: 4 right:10 2 …
Problem Statement The problem “Non-overlapping sum of two sets” states that you are given two arrays as input values as arrA[] and arrB[] of the same size n. Also, both of the arrays have distinct elements individually and some common elements. Your task is to find out the total sum …
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 “Sort a stack using recursion” states that you are given a stack data structure. Sort its elements using recursion. Only the below-listed functions of the stack can be used – push(element) – to insert the element in the stack. pop() – pop() – to remove/delete the …
Problem statement The problem “Sorting array using Stacks” states that you are given a data structure array a[ ] of size n. Sort the elements of the given array using stack data structure. Example 2 30 -5 43 100 -5 2 30 43 100 Explanation: The elements are sorted in …
Problem Statement The problem “Sort a stack using a temporary stack” states that you are given a stack data structure. Sort the elements of the given stack using a temporary stack. Example 9 4 2 -1 6 20 20 9 6 4 2 -1 2 1 4 3 6 5 …
Problem Statement Suppose we have an integer array. The problem “Distinct adjacent elements in an array” asks to determine if it is possible to get the array in which all the adjacent numbers are distinct or not by swapping up two adjacent or neighbour elements in an array if it …
Problem Statement The problem ” Rearrange an array such that ‘arr[j]’ becomes ‘i’ if ‘arr[i]’ is ‘j’ ” states that you have an “n” sized array containing integers. The numbers in the array are in a range of 0 to n-1. The problem statement asks to rearrange the array in …
