Which sorting algorithm is best if it is already sorted & why?
But what if the data is almost sorted, with just a few elements out of place? Which algorithm would be best then?
In the case where the data is almost sorted, but just a few elements are out of place, then the best sorting algorithm would be Selection Sort or Bubble Sort. These algorithms have time complexities of O(N^2), which is not the most efficient, but they perform well in almost sorted data because they have to make fewer swaps.
