Use of Lowest Common Multiple (LCM) Test

The problem asks to find the largest element in a set S, where S is built by taking the LCM of every pair of adjacent elements in a given array arr of positive integers. The LCM (Least Common Multiple) of two numbers is the smallest positive integer that is a multiple of both of them.

The problem tests the attendee's understanding of the concept of LCM, the ability to compute it efficiently, and the ability to manipulate arrays. To solve the problem, the attendee needs to iterate through the array and compute the LCM of each pair of adjacent elements. Then, the largest element of the resulting set S needs to be found.
