Why sorting an array is difficult?

The most common reason for students having difficulty with writing and implementing sorting algorithms is that they don’t take into account the fact that the computer can only compare two data values at a time. Thus, a computer sorting algorithm is different from the one a human might use at first glance.

How to check if array can be sorted with one swap?

If there are no mismatches, the array is already sorted. If there are exactly 2 mismatches, we can swap the terms that are not in the position to get the sorted array. An efficient solution is to check in linear time. Let us consider different cases that may appear after one swap. We swap adjacent elements.
