Bubblesort
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.
Insertion Sort
A sorting technique that builds the sorted array one element at a time, inserting each new element into its proper position among already-sorted elements.
- Time complexity is Quadratic, i.e. O(n^2)
- Space complexity is Constant, i.e. O(1)
Selection Sort
Selection sort is a comparison-based sorting algorithm that divides the input list into two parts: the sublist of items already sorted, which is built up from left to right at the front (left) of the list, and the sublist of items remaining to be sorted that occupy the rest of the list. Initially, the sorted sublist is empty and the unsorted sublist is the entire input list. The algorithm proceeds by finding the smallest (or largest, depending on sorting order) element in the unsorted sublist, exchanging (swapping) it with the leftmost unsorted element (putting it in sorted order), and moving the sublist boundaries one element to the right.
