Which of the following sorting methods would be most suitable for sorting a list which is almost sorted?ans.selection sortmerge sortinsertion sortbubble sort

The most suitable sorting method for sorting a list which is almost sorted is the Insertion Sort.

Here's why:

1. Selection Sort: This method is not efficient for an almost sorted list because it always searches for the smallest or largest element in the list and swaps it with the first unsorted element, regardless of whether the list is already almost sorted or not.

2. Merge Sort: This method is a very efficient sorting algorithm with time complexity O(n log n), but it doesn't take advantage of the fact that the list is almost sorted. It still divides the list into two halves, sorts them separately and then merges them.

3. Insertion Sort: This method is very efficient for almost sorted lists. It works by taking one element at a time and inserting it in its correct position in the sorted part of the list. If the list is already almost sorted, this means that each element is likely to be close to its correct position, so the algorithm will be able to sort the list with a minimal number of operations.

4. Bubble Sort: This method is not efficient for an almost sorted list because it repeatedly swaps adjacent elements if they are in the wrong order, regardless of whether the list is already almost sorted or not.

So, the answer is Insertion Sort.
