Algorithm-selection sort


Algorithm SelectionSort(data[],n)

 

For pass = n-1 down to 1

a.Select largest among data[0] .. data[pass]

b.Interchange largest and data[pass]

End

 

Explanation

 

  1. Selection sort selects the largest(or smallest)element from the list to be sorted and place it in its correct position.

  2. If the largest element is taken, then it is placed in its last position.

  3. As in the previous types of sorts ,we find that one element moves to the correct position in evey pass.

  4. With every pass the sorted portion of the list grows by 1 and the unsorted portion shrinks by 1.

  5. We need to repeat the process n times.
  6.
