Greedy algorithms:The class of algorithms that make locally optimal choices at each step with the hope that these choices will lead to a globally optimal soluti

1. What Are We Talking About?The 132 pattern is a problem where we need to find a subsequence of three numbers in an array (nums[i], nums[j],&nbs

Situation:You are given a sorted array of integers where every element appears exactly twice, except for one element that appears only once.

In the world of computer science and mathematics, some problems are deceptively simple to describe but incredibly challenging to solve.One such problem is the&n

Greedy algorithm only applies to the optimization problem.Greedy algorithm makes the decision at every point choosing the local minimum or maximum depending on

If you stack several restricted Boltzmann machine on the top of each other then we form a deep belief networkInput layers -> suplied to 1st RBM -> inputs

In this thread we will see how a single dynamic programming (DP) approach can be adapted to solve multiple seemingly different problems. By understand

A Singleton is a design pattern that ensures a class has only one instance (object) throughout the entire application and provides a global point to access it.L

Bayes' Rule:A fundamental concept in probability theory. It allows us to update our belief about an event based on new evidence.probability of an event A, given

Binary tree, Binary search tree, full and complete binary tree we can combine these ideas together so that we can learn a new assistant data structure which is

Every components starts simple enough, a few fields. Some basic state, clean, straightforward and manageable.But then reality hits.More fields. More validation.

Why Trie Data Structure?Whenever you start typing in modern applications - whether it's a search bar, messaging app, or navigation system, there's likely a Tri
