Stacks are a fundamental data structure in computer science, often used for their Last-In-First-Out (LIFO) properties. One interesting problem that can be encountered while working with stacks is checking whether the elements of a stack are pairwise consecutive. In this article, we will learn to solve this problem using Java, ensuring an efficient and clear solution. Problem Statement Given a stack of integers, the task is to determine if the elements of the stack are pairwise consecutive. Two elements are considered consecutive if they differ by exactly 1. Input 4, 5, 2, 3, 10, 11 Output Are elements pairwise consecutive?true ...
