Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller elements 'bubble' to the top of the list. Although the algorithm is simple, it is too slow and impractical for most problems even when compared to insertion sort. It can be practical if the input is usually in sort order but may occasionally have some out-of-order elements nearly in position.

Circular Sort (often called Cycle Sort) is an in-place sorting algorithm that minimizes memory writes by placing elements in their exact positions.
Cyclic Sort is an O(n) in-place sorting algorithm specifically designed for arrays containing numbers in a given continuous range (e.g., 1 to N).
Heap Sort is an efficient comparison-based sorting algorithm based on a binary heap data structure. It sorts by building a max-heap from the data and repeatedly extracting the maximum element.

Insertion Sort is a simple sorting algorithm that builds the final sorted array one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort.

Merge Sort is a divide-and-conquer sorting algorithm that divides the array into smaller subarrays, sorts them recursively, and then merges them back together in sorted order. It is a stable and efficient algorithm with $O(n log n)$ time complexity in all cases.
The Product of Array Except Self problem requires calculating the product of all elements in an array except for the element at the current index. The challenge is to perform this without using division and in O(n) time complexity.

Quick Sort is a highly efficient and commonly used sorting algorithm that employs a divide-and-conquer strategy. It is well-suited for large datasets and typically outperforms other algorithms like insertion sort and bubble sort.

Selection Sort is an in-place comparison sorting algorithm that divides the input list into two parts: the sublist of items already sorted and the sublist of items remaining to be sorted. It repeatedly finds the minimum element from the unsorted part and puts it at the beginning of the unsorted part. The algorithm maintains two subarrays in a given array. The subarray which is already sorted and the remaining subarray which is unsorted. In every iteration of selection sort, the minimum element from the unsorted subarray is picked and moved to the sorted subarray.

Shell Sort is a generalization of insertion sort that allows the exchange of far-apart elements. It uses a gap sequence to progressively reduce the gap and efficiently sort the array. It offers improved performance compared to simple sorting algorithms with O(n log n) to O(n log² n) time complexity.

A comprehensive developer's guide to C++ arrays. Learn memory allocation mechanics, declaration, initialization styles, boundary limits, and multi-dimensional grid structures.
An array is a collection of items stored at contiguous memory locations. It is a data structure that stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
