Comparison sorts | Sorting algorithms
Cycle sort is an in-place, unstable sorting algorithm, a comparison sort that is theoretically optimal in terms of the total number of writes to the original array, unlike any other in-place sorting algorithm. It is based on the idea that the permutation to be sorted can be factored into cycles, which can individually be rotated to give a sorted result. Unlike nearly every other sort, items are never written elsewhere in the array simply to push them out of the way of the action. Each value is either written zero times, if it's already in its correct position, or written one time to its correct position. This matches the minimal number of overwrites required for a completed in-place sort. Minimizing the number of writes is useful when making writes to some huge data set is very expensive, such as with EEPROMs like Flash memory where each write reduces the lifespan of the memory.

Cycle Sort Algorithm - Sorting with Minimal Writes
The cycle sort algorithm is a sorting algorithm that uses the fact that any permutation is a product of disjoint cycles to sort an array with the minimum number of writes. I'm gonna use an example with cars to explain the idea. Then I'll write the code and explain how it works. I'll also s
