Shell Sort is an improved version of Insertion Sort that helps data move faster toward its correct position. Instead of comparing and shifting elements one step at a time, Shell Sort allows elements to jump over long distances early on. This simple idea makes sorting much quicker, especially for medium-sized datasets that are not already […]

Bucket Sort is a simple and interesting sorting algorithm that works best when numbers are spread evenly over a known range. Instead of comparing every number with every other number, Bucket Sort divides values into small groups called buckets, sorts each bucket, and then joins everything back together. This approach makes the algorithm easy to

Radix Sort is a special sorting algorithm that works very differently from comparison-based sorts like Bubble Sort or Heap Sort. Instead of comparing numbers directly, Radix Sort looks at each digit of the numbers, starting from the least significant digit and moving toward the most significant one. By sorting numbers digit by digit, Radix Sort

Heap Sort is a powerful and efficient sorting algorithm that is commonly taught after beginners learn simpler sorting methods. The idea behind Heap Sort comes from a data structure called a heap, which is a special kind of binary tree. In Heap Sort, the largest or smallest value is always kept at the top, making

Merge Sort is a powerful and efficient sorting algorithm that works much faster than simple algorithms like Bubble Sort or Insertion Sort when the data becomes large. The main idea behind Merge Sort is to divide a list into smaller parts, sort those parts, and then merge them back together in the correct order. Because

Quick Sort is one of the most popular and widely used sorting algorithms in computer science. It is known for being very fast in practice and is often the first “advanced” sorting algorithm beginners learn after simple ones like Bubble Sort or Insertion Sort. The core idea of Quick Sort is to pick one element

Selection Sort is a simple and easy-to-understand sorting algorithm that works well for beginners. The idea behind Selection Sort is very straightforward. The algorithm repeatedly looks for the smallest value in a list and moves it to the correct position. Step by step, the list becomes sorted from left to right. Because of this clear

Insertion Sort is one of the most beginner-friendly sorting algorithms you can learn. It works in a very natural way, similar to how people sort playing cards in their hands. You take one value at a time and insert it into the correct position among the already sorted values. Because of this simple idea, Insertion

Bubble Sort is one of the simplest sorting algorithms you can learn as a beginner. It works by comparing two nearby values and swapping them if they are in the wrong order. This process repeats again and again until the entire list becomes sorted. Because of this repeated swapping, the biggest values slowly move to

Breadth-First Search (BFS) is a fundamental algorithm used to explore nodes in a graph or tree level by level. Unlike Depth-First Search (DFS), which dives deep along a branch before backtracking, BFS starts from a source node and visits all neighboring nodes before moving to the next level. This makes BFS ideal for finding the
