We train a model on handwritten digit classification. 99% accuracy. Then we train the same model on a new task — say, fashion item recognition. We go back and test it on digits. 34% accuracy. It has c
At the core of data structures and algorithms are fundamental mathematical principles that guide their design and implementation. This article explores key math concepts essential for mastering data s
Imagine you've just created an algorithm, and it works lightning-fast on your brand-new computer. You're thrilled with the results and can't wait to share your success, so you ask your friend to give it a try. However, when your friend runs the same ...
A Problem Let’s start with a problem: I need to print first 10 natural numbers. There are several ways to solve this problem. But let's say we need to solve it using functions without using loops or calling a function more than once. The simplest way...
Cyclic sort is an in-place and unstable sorting algorithm that is specifically designed to efficiently sort arrays where numbers are in a known range like from 1 to N. How does it work? Let’s take the following array as an example. We need to sort it...
Insertion sort is a simple comparison-based sorting algorithm that sorts by repeatedly inserting elements into their correct position. Let's explore how it works in detail. What is Insertion Sort? Insertion Sort is a comparison sort algorithm. It div...
Selection Sort is a simple sorting algorithm that repeatedly finds the smallest (or the largest) element from the unsorted part and moves it to its correct position. What is Selection Sort? Selection sort is a comparison sort algorithm. It repeatedly...
Bubble sort (also called as Sinking Sort and Exchange Sort) is a straightforward sorting algorithm that operates by repeatedly comparing and swapping adjacent elements if they are in the wrong order. What is Bubble Sort? Bubble Sort is a comparison s...
