The problems read as follows, for contains duplicates:
Given an integer array
true if any value appears at least twice in the array, and return

Stacks are a useful data structure that holds a list of elements. A stack works in a “last in”, “first out” principle meaning that the most recently added element is the first one to remove. The stack has two main methods that we use, .push() and .pop().
const reverse =…
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. In computer science, big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size…
