Questions & Step-by-Step Solutions
In a stack implemented using an array, what is the time complexity of the push operation?
Step 1: Understand what a stack is. A stack is a data structure that follows the Last In First Out (LIFO) principle.
Step 2: Know that a stack can be implemented using an array, where elements are added and removed from the end of the array.
Step 3: Identify the push operation. The push operation adds an element to the top of the stack (the end of the array).
Step 4: Realize that adding an element to the end of an array is a simple operation that does not depend on the number of elements already in the stack.
Step 5: Conclude that the time complexity for the push operation is O(1), meaning it takes constant time regardless of the stack size.
