What is the time complexity of pop in Python?

WebThe worst-case time complexity is linear. Similarly, searching for an element for an element can be expensive, since you may need to scan the entire array. In this Python code example, the linear-time pop (0) call, which deletes the first element of a list, leads to highly inefficient code: Warning: This code has quadratic time complexity . WebCase 1: To delete the first element from a list of 10000 elements using pop (). Case 2: To delete an element at 4900th index (element 5000, refer to the time complexity example of remove ()) from the list of 10000 elements using pop ().

Time and Space Complexity of Stack - OpenGenus IQ: …

WebPop() for the last element ought to be O(1) since you only need to return the element referred to by the last element in the array and update the index of the last element. I would expect pop() for an arbitrary element to be O(N) and require on average N/2 operations since you would need to move any elements beyond the element you are removing one … WebTime complexity of pop() O(1) Time complexity of is_empty() O(1) Advantages of implementing stack using linked list.
