Min and Max element in array

In this article, we have explained how to use a Divide and Conquer approach to find the Minimum and Maximum element in array using the theoretically minimum number of comparisons.

Table of contentsProblem or StatementMethods to approach the SolutionApproach-1: Using Brute forceApproach-2: Using Divide and ConquerConclusionLet's understand the Problem

Given an array a[] of size 'n', we need to find the minimum and maximum elements in the array using minimum comparisions.

For example:Let...

Print all combinations of factors

In this article, we will discuss about the algorithms to print every combination of factors of a given number (all factorization). We have explored recursive and partially iterative approach.

What we'll see,

Problem StatementIterative ApproachRecursive ApproachConclusionReferencesProblem Statement

We have to design and implement an algorithm which prints all the unique combinations of factors of the given number. For example, let the number given be 16, therefore, the output should be as ...

Generate 0 and 1 with 25% and 75% probability

Given a function that generates 0, 1 50% of the time (like most of the random function in modern programming languages do), how can we design a function that return 0, 1 25%, 75% of the time?

Let's lay out a rule: random functions that return floating points are not allowed to be used. One can only use the said function that returns 0, 1 in equal probability since one can easily set a floating point as a threshold and return 0, 1 according to the exceedance threshold values.

Commonly Used Neural Networks

Neural Networks are soft computing systems which aim at simulating the function of the human brain. Since the human brain is fantastic at reasoning, processing and learning in environments of noise, uncertainty and imprecision; implementing Neural Networks allows us to solve very complex, mathematically ill-defined problems using very simple computational operations (such as addition, multiplication, and fundamental logic elements). They are essentially networks consisting of multiple artificial...
