Insertion sort is the simplest sorting algorithm in which the elements are transferred to the right position one at a time. An insertion sort has many benefits because of simplicity and low overhead.
In an Insertion sort, the first element in the array is considered as sorted. In an insertion sort, each element in the array is checked with the previous elements, which results in a growing sorted output array. With every iteration, the insertion sorting algorithm removes one element at a time and finds it's appropriate location within the sorted array and inserts it there in the sorted list. The iteration continues until the whole list is sorted.
