This technical problem involves finding the median of a list of numbers in Python. An example input would be [1, 2, 3, 4, 5], and the expected output would be 3 .
This Python class implements a stack using a list. The stack supports the following operations: push, pop, size, and isEmpty.
This technical problem asks the reader to write a Python class that implements a stack using a linked list. The stack should have methods for pushing an integer onto the stack, popping and returning the top element of the stack, and checking if the stack is empty.
This technical problem deals with creating a Python class named "Foo" with an instance variable named "value". The class also has two methods, "double" and "triple", which multiply the value by 2 and 3, respectively.
Implement a min heap in Python by creating a Python class with the following methods: insert(self, val), remove_min(self), and peek_min(self).
This technical problem explains how to create a calculator class in Python that can perform addition, subtraction, multiplication, and division operations. The calculator takes two operands (numbers) and an operator as input, and returns the result of the operation.
This technical problem deals with implementing a stack data structure in Python using a class. The class should have two methods: push, which adds an item to the top of the stack, and pop , which removes and returns the top item from the stack. If the stack is empty, pop should raise an IndexError.
