Questions & Step-by-Step Solutions
If a stack is implemented using an array, what is the time complexity of resizing the array when it is full?
Step 1: Understand that a stack is a data structure that stores elements in a last-in, first-out (LIFO) manner.
Step 2: Know that when a stack is implemented using an array, it has a fixed size.
Step 3: Realize that when the stack is full and you want to add another element, you need to resize the array.
Step 4: Resizing the array means creating a new, larger array to hold more elements.
Step 5: Copy all the existing elements from the old array to the new array.
Step 6: Understand that copying all elements takes time proportional to the number of elements, which is O(n), where n is the number of elements in the stack.
