Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time by comparisons. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort. However, insertion sort provides several advantages:
It improves upon insertion sort by moving out of order elements more than one position at a time. The concept behind Shellsort is that insertion sort performs in O ( k n ) {\displaystyle O(kn)} time, where k is the greatest distance between two out-of-place elements.
Insertion sort: Scan successive elements for an out-of-order item, then insert the item in the proper place. Selection sort : Find the smallest (or biggest) element in the array, and put it in the proper place.
Insertion sort is very similar in that after the kth iteration, the first elements in the array are in sorted order. Insertion sort's advantage is that it only scans as many elements as it needs in order to place the + st element, while selection sort must scan all remaining elements to find the + st element.
Insertion maintains the balanced property of the tree. [5] To insert into a 2-node, the new key is added to the 2-node in the appropriate order. To insert into a 3-node, more work may be required depending on the location of the 3-node. If the tree consists only of a 3-node, the node is split into three 2-nodes with the appropriate keys and ...

Comparison-based sorting algorithms have traditionally dealt with achieving an optimal bound of O(n log n) when dealing with time complexity.Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence.
The numbers mean a tree where every node with children (internal node) has either two, three, or four child nodes: a 2-node has one data element, and if internal has two child nodes; a 3-node has two data elements, and if internal has three child nodes; a 4-node has three data elements, and if internal has four child nodes;
