Question
What is the time complexity of the peek operation
(accessing the top element without removing it) in a stack implemented using a singly linked list?Solution
In a singly linked list implementation of a stack, the top of the stack is typically represented by the head of the list. Accessing the head element (peek operation) takes constant time, O(1).
