## Shell SortSorting Algorithm

In this tutorial we will be learning about Shell sort algorithm. It is a generalisation of the insertion sort. In this sorting algorithm we compare elements that are distant apart rather than adjacent. We start by comparing elements that are at a certain distance apart. So, if there are N elements then we start with a value gap < N. In each pass we keep reducing the value of gap till we reach the last pass when gap is 1. In the last pass shell sort is like insertion sort.

It is the interest calculated on the Principal P at a given rate R for a given time period T. And the formula for simple interest is SI = (PxRxT)/100
