![]() Pass – 4 (left), Pass – 5 (middle) and Pass 6 (right) The following figure shows the simulation to sort characters of word “DESIGN” Let us sort the letters of word “ DESIGN” in alphabetical order using selection sort. Sorting begins from the beginning.Īt the end of the first pass, minimum element seats on the first location, in the second pass, second minimum element seats on the second location and so on Example k items are sorted at the end of the k-th pass. In each iteration i, Selection sort identifies the smallest element in an unsorted list and swaps it with the i-th element in the list. ![]() When the unsorted section gets empty, the process comes to a halt. At every step, algorithm finds minimal element in the unsorted part and adds it to the end of the sorted one. The sorted section is initially empty, whereas the unsorted section includes the whole array. The array is split into two sections, one sorted and one unsorted. Selection sort is known for its simplicity, and it outperforms more complex algorithms in some cases, particularly when auxiliary memory is limited. However, its running time is quadratic, making it unsuitable for a long list. It performs maximum (n – 1) swaps on a list of size n. ![]() it is easy, and it has the obvious benefit of having the fewest swaps of any algorithm. ![]() Selection sort, like bubble sort, is a comparison-based in-place sorting algorithm. ![]()
