//|------------------------------------------------------------------|
//|  insertion sort is a simple sorting algorithm that builds the    |
//|final sorted array (or list) one item at a time. it is much less  |
//|efficient on large lists than more advanced algorithms such as    |
//|quicksort, heapsort, or merge sort.                               |
//|  when people manually sort cards in a bridge hand, most use a    |
//|method that is similar to insertion sort.                         |
//|  insertion sort provides several advantages:                     |
//|  | simple implementation: jon bentley shows a three-line c       |
//|version, and a five-line optimized version                        |
//|  | efficient for (quite) small data sets, much like other        |
//|quadratic sorting algorithms                                      |
//|  | more efficient in practice than most other simple quadratic   |
//|(i.e., o(n^2)) algorithms such as selection sort or bubble sort   |
//|  | adaptive, i.e., efficient for data sets that are already      |
//|substantially sorted: the time complexity is o(kn) when each      |
//|element in the input is no more than k places away from its sorted|
//|position                                                          |
//|  | stable; i.e., does not change the relative order of elements  |
//|with equal keys                                                   |
//|  | in-place; i.e., only requires a constant amount o(1) of       |
//|additional memory space                                           |
//|  | online; i.e., can sort a list as it receives it               |
