## Find smallest range with at-least one element from each of the given lists

Given M sorted lists of variable length, efficiently compute the smallest range that includes at-least one element from each list.

Coding made easy

Given M sorted lists of variable length, efficiently compute the smallest range that includes at-least one element from each list.

Given an array and positive integer k, find k’th smallest element in the array.

Given a k-sorted array that is almost sorted such that each of the N elements may be misplaced by no more than k positions from the correct sorted order. Find a space-and-time efficient algorithm to sort the array.

Implement heap data structure.

In this article, we will introduce a very important data structure Priority Queues and discuss how we can implement them using (Binary) Heaps.

A stack is a linear data structure that serves as a collection of elements, with three main operations:

Given a set of tasks with deadlines and total profit earned on completion of a task, find maximum profit earned by executing the tasks within the specified deadlines. Assume any task will take one unit of time to execute and any task can’t execute beyond its deadline. Also, only one task can be executed at …
