Questions & Step-by-Step Solutions
Which of the following operations is not typically associated with a stack?
Step 1: Understand what a stack is. A stack is a data structure that follows the Last In, First Out (LIFO) principle, meaning the last item added is the first one to be removed.
Step 2: Identify common operations associated with a stack. The main operations are 'push' (to add an item) and 'pop' (to remove the top item).
Step 3: Understand what a queue is. A queue is a data structure that follows the First In, First Out (FIFO) principle, meaning the first item added is the first one to be removed.
Step 4: Identify common operations associated with a queue. The main operations are 'enqueue' (to add an item) and 'dequeue' (to remove the front item).
Step 5: Compare the operations of stacks and queues. Notice that 'dequeue' is an operation for queues, not stacks.
Step 6: Conclude that 'dequeue' is not typically associated with a stack.
