While sorting is a simple concept, it is a basic principle used in complex computer programs such as file search, data compression, and path finding. Algorithm now we have a bigger picture of how this sorting technique works, so we can derive simple steps by which we can achieve insertion sort. In other words, an insertion sort helps in building the final sorted list, one item at a time, with the movement of higherranked elements. I know both are on 2, but it seems to me that bubble sort just bubbles the maximum value of the array to the top for each pass, while insertion sort just sinks the lowest value to the bottom each pass.

Try clicking bubble sort for a sample animation of sorting the list of 5 jumbled integers with duplicate above. Each new position is like the new card handed to you by the dealer, and you need to insert it into the correct place in the sorted subarray to the left of that position.
As we mentioned above that insertion sort is an efficient sorting algorithm, as it does not run on preset conditions using for loops, but instead it uses one while loop, which avoids extra steps once the array gets sorted. External sorting, radix sorting, string sorting, and linked list sorting all wonderful and interesting topicsare deliberately omitted to limit the scope of discussion. Using linear search, find the location in the sorted portion where the 1st element of the unsorted portion should be inserted move all the elements after the insertion location up one position to make space for the new element. Here, a sublist is maintained which is always sorted. Insertion sort is a sorting algorithm in which the elements are transferred one at a time to the right position.
