Permutation Sort is a sorting algorithm based on generating all permutations of the given input and then selecting the sorted one. While conceptually simple, it’s impractical for large datasets due to its extremely high time complexity.   How Permutation Sort Works: Find the Range: Identify the minimum and maximum values in the input array to Read More …

Bucket Sort is a distribution-based sorting algorithm that works by dividing the input array into several “buckets,” sorting each bucket individually, and then combining the results. It is effective when the input data is uniformly distributed over a range.   How Bucket Sort Works: Create Buckets: Divide the input elements into several groups (buckets). The Read More …

Radix Sort is a non-comparative integer sorting algorithm that sorts numbers by processing individual digits. It processes the digits from the least significant digit (LSD) to the most significant digit (MSD) or vice versa. Radix Sort works by distributing numbers into buckets according to each digit, then recombining them in a sorted order.   How Read More …

Selection Sort is a simple comparison-based sorting algorithm. It divides the list into two parts: a sorted part and an unsorted part. The algorithm iteratively selects the smallest (or largest, depending on the desired order) element from the unsorted part and moves it to the sorted part.   How Selection Sort Works: Initialization: Start with Read More …

Counting Sort is a non-comparison-based sorting algorithm that sorts integers by counting the occurrences of each unique element and using these counts to determine the positions of elements in the sorted array. It is particularly effective for sorting integers when the range of values (difference between the smallest and largest numbers) is not significantly larger Read More …

Bubble Sort is a simple comparison-based sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order. This process is repeated until the list is sorted.   How Bubble Sort Works: Compare Adjacent Elements: Start from the first element and compare it with the next Read More …

Insertion Sort is a simple comparison-based sorting algorithm that builds the final sorted array one element at a time. It works by iteratively taking an element from the unsorted portion of the array and inserting it into the correct position within the sorted portion.   How Insertion Sort Works: Build a Max Heap: Arrange the Read More …

Heap Sort is a comparison-based sorting algorithm that uses a binary heap data structure. It first transforms the input array into a max-heap (where the largest element is at the root) and then repeatedly extracts the largest element, placing it at the end of the array while adjusting the heap. This process continues until the Read More …

Merge Sort is a stable and efficient sorting algorithm that uses the divide-and-conquer strategy. It divides the input array into two halves, recursively sorts each half, and then merges the sorted halves to produce the final sorted array. This process ensures that the algorithm always has a time complexity of O(n log n) for all Read More …

Quick Sort is a highly efficient sorting algorithm that employs the divide-and-conquer strategy. It works by selecting a “pivot” element from the array and partitioning the other elements into two groups: those less than the pivot and those greater than the pivot. The process is recursively applied to the sub-arrays formed by the partition. The Read More …
