What is the Quickselect algorithm? The Quickselect algorithm is a computer algorithm designed to find the kth (e.g. smallest or largest) element from an unordered list. It is based on the idea behind the Quicksort algorithm, invented by the same author, Sir Charles Anthony Richard (Tony) Hoare. Here, k stands for the index of an

Do you train for your upcoming coding interview? This question was asked by Google as reported in multiple occasions by programmers all around the world. Can you solve it optimally? Let’s dive into the problem first. Problem Formulation Given an integer array or Python list nums and an integer value k. Find and return the

Iterables and iterators are everywhere in Python. We usually aren’t aware of the iterators because the syntax of python hides them from us. Almost every time we manipulate a sequence type (strings, lists, tuples, sets, arrays, etc.), we’re using an iterator behind the scenes. An iterable represents a sequence of values each of which is

Today’s tutorial will introduce two slightly more advanced concepts of closures and decorators in Python. We’ll explain what they are, how each is defined, and where and how they will help in your coding. Nested Functions I’m sure you are all familiar with functions, and some of you may have used, or heard of, nested

If there is one subject in Python that creates confusion, it is that of generators. Generators are functions, but they have several differences from the ordinary functions you and I use daily. Today, we’ll be taking a gentle immersion into the world of generators to understand what they are, how they differ from ordinary functions,

A namespace is a filing system used by Python to track all the names given to objects when you write a program. When I first began trying to understand namespaces in Python, the tutorials I came across were confusing and less than helpful in their descriptions. Today I will take you on a logical and
