This Python class implements a stack using a list. The stack supports the following operations: push, pop, size, and isEmpty.
This problem is about writing a function that returns the sum of the elements in a list. If the list is empty, the function should return 0.
The problem is to find the length of the longest increasing subsequence in an array. For example, given the array [10, 22, 9, 33, 21, 50, 41, 60, 80], the longest increasing subsequence would be of length 6, and would be [10, 22, 33, 50, 60, 80].
The function should take a list of integers as input and return the sum of the integers in the list that are divisible by 3.
This technical problem deals with retrieving the page title from a URL using Python. The given URL is http://www.google.com and the expected output is simply "Google".
Given a list of integers, this function will return the sum of the odd integers in the list.
This technical problem deals with finding all possible permutations of a list of integers in Python. An example input would be [1, 2, 3] and the corresponding output would be [[1 , 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1] ].
This technical problem deals with finding the sum of all the elements in a list of integers. An example input would be [1, 2, 3, 4, 5], and the corresponding output would be 15.
