Shell Sort

Reading Time: 1 minute

Definition

Shell Sort is a variation of the Insertion Sort. Shell Sort is very fast algorithm that is compact in code size. A gap in other words a distance is set that will be used between the elements in the array
Sub lists are made out of the elements in the gap and the sub lists are compared. In the comparison lower element goes to the left and greater is on the right.
The process continues, later on the gap gets smaller until it becomes one. After the gap reaches to one, then the Insertion Sort is applied to sort the rest. Depending of this gap the time complexity of the algorithm varies.
