``````// simplesort.go
// description: Implementation of a simple sorting algorithm
// details:
// A simple sorting algorithm that look counter intuitive at first glance and very similar to Exchange Sort
// An improved version is included with slight changes to make the sort slightly more efficient
// reference: https://arxiv.org/abs/2110.01111v1
// see sort_test.go for a test implementation, test function TestSimple and TestImprovedSimple

// swap arr[i] and arr[j]
arr[i], arr[j] = arr[j], arr[i]

// ImprovedSimple is a improve SimpleSort by skipping an unnecessary comparison of the first and last.
// This improved version is more similar to implementation of insertion sort
