Description: Write a program that reads 10 integers and displays them in the reverse of the order in which they were read. If two consecutive numbers are identical, then only display one of them. Implement your program using only stack and not arrays or queues.

Key Concepts

Stack Data Structure

A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle, meaning the most recently added element is the first one to be removed. This property makes stacks ideal for reversing the order of input, as elements can be pushed onto the stack and then popped off to produce the reversed sequence.

Stack Operations (Push and Pop)

Stack operations are fundamental to using the stack data structure. The push operation adds an element to the top of the stack, and the pop operation removes the element from the top. These operations are used to manage the order of elements and enable the reversal process by ensuring that the last element read is the first element accessed when reading back.

Reversing Order with Stacks

Reversing a sequence of elements is naturally supported by stacks due to their LIFO behavior. By pushing each element onto the stack as it is read, the order is inverted when the elements are subsequently popped off the stack, achieving the desired reverse order display.

Duplicate Elimination in Sequences

Duplicate elimination involves checking for consecutive duplicate values and displaying only one instance of such duplicates. This concept requires conditional logic to determine if the next element is identical to the current one, thereby ensuring that repeated adjacent elements are not redundantly processed or displayed.
