 ====== Insertion sort ====== ====== Insertion sort ======
 +Insertion sort is a simple sort algorithm that sorts a list by building a sorted list front to back. It repeatedly moves the next unsorted element towards the front of the list until it is in a sorted position. Although it has a worst case of $O(n^2)$ it is often the algorithm of choice for small data sets or when the data is almost sorted due to its low overhead and that the algorithm is both stable and adaptive.
 +===== Properties =====
 +  * Stable
 +  * $O(1)$ space
 +  * $O(n^2)$ comparisons and swaps
 +  * Adaptive, $O(n)$ when nearly sorted
