Exploring Simple Sorting Algorithms in Swift

When it comes to data management, sorting is essential. Our goal in sorting is to go from disorder to order. This is accomplished by arranging facts in a logical sequence so that we know where to look for information. Sequences are easily done with integers, but they can also be achieved with characters (for example, alphabets) and other sets such as binary and hexadecimal numbers. In the following examples, we'll use various strategies to sort the array:

It's simple to visualize the problem with a shortlist. We can use an invariant to arrange our set into an ordered sequence. Invariants are assumptions that do not alter throughout execution. Consider the insertion sort algorithm to see how this works.

Insertion Sort

Insertion sort is a fundamental algorithm in computer science. By iterating through a collection, the algorithm rates elements and positions them based on their value. The set is split into sorted and unsorted halves, and the process is repeated until all elements are sorted:

Bubble Sort

Another prominent sorting technique is the bubble sort. The bubble sort method, like insertion sort, combines a sequence of steps with an invariant. The function operates by comparing two values. When the values are compared, the position of the largest value is swapped with the position of the smaller value. When this "bubbling" effect is repeated enough times, it ultimately sorts all of the entries in the list:

Sort Selection

The selection sort algorithm, like the bubble sort, ranks elements by iterating through a collection and swapping elements based on their value. The set is split into sorted and unsorted halves, and the process is repeated until all elements are sorted:
