//We start selection sort by scanning the entire list to //find its smallest element and exchange it with the first //element,putting the smallest element in its final position in //the sorted list. Then we scan the list,starting with the second //element,to find the smallest among the last n-1 elements //and exchange it with the second element,putting the second //smallest element in its final position. //Generally,on the ith pass through the list,which we number from 0 to //n-2,the algorithm searches for the smallest item among the n-i elements //and swap it with A. //After n-1 passes,the list is sorted.
