What should be the time complexity of the isEmpty(), size(), and toString() methods?

What will be an ideal response?


Using the count variable, the size method is O(1) and simply returns the value of count. The isEmpty() method simply checks to see if size is equal to zero, so it is also O(1). The toString() method looks at each element in the stack once, so its time complexity is O(n), where n is the number of elements in the stack.
