I dive into solving the “242. Valid Anagram” problem from LeetCode using Python. I demonstrate a step-by-step approach to checking if two strings are anagrams by leveraging character frequency counts and dictionary comparisons.
I solve the “1046. Last Stone Weight” problem from LeetCode using Python. I demonstrate how to efficiently solve this challenge by simulating a max-heap with Python’s heapq module. The video walks through the steps of converting stone weights into a heap, processing the two heaviest stones, and handling the results to determine the final weight…
Renaissance Technologies, led by James Simons, is a hedge fund known for its incredible success using quantitative (math-based) trading strategies. Unlike traditional traders, Renaissance uses data, mathematical models, and high-speed algorithms to beat the market. Let’s break down how they do it in simple terms. 1. Data-Driven Trading Renaissance analyzes massive amounts of data, from…

There used to be a time when I used to be confused about the differences between functions and methods. Functions and methods are fundamental concepts in programming that help to organize code, promote reusability, and improve readability. Understanding how to create and use them is essential for any programmer. This post will explain what functions…
In this video, we dive into the implementation of a Trie (Prefix Tree) in Python, a fundamental data structure for efficient prefix-based queries. Watch as we break down the process of inserting words, searching for exact matches, and checking for prefixes, all while highlighting key algorithms and practical applications like autocomplete and spell checking. Python…
