Sorting Array Elements
Having data in a random jumble is messy. In Sorting Array Elements, you are going to fix that by arranging an array of integers so they go from the smallest to the largest.
There are many ways to do this, but the core idea is to compare numbers and swap their positions until everything is in a perfect ascending line. It is a classic challenge that helps you think about how to organize information efficiently within your logic.
If you start with [5, 1, 4, 3, 2], your finished result should be a neat [1, 2, 3, 4, 5]. It might take a few passes through the list, but once you are done, any computer or human will find it much easier to work with that sorted data!
Algorithm Flow
Solution Approach
To sort a list, we can use the Selection Sort algorithm. It is an intuitive $O(n^2)$ algorithm that builds the sorted list one element at a time.
On each iteration of the outer loop, the inner loop finds the smallest element in the remaining unsorted portion of the array. Once found, this minimum element is swapped with the element at the current boundary variable i, effectively expanding the sorted portion of the array by one.
