Another simple sort is the odd-even sort. The idea is to repeatedly make two passes through the array. On the first pass you look at all the pairs of items, a[j] and a[j+1], where j is odd (j = 1, 3, 5, …). If their key values are out of order, you swap them. On the second pass you do the same for all the even values (j = 2, 4, 6, …). You do these two passes repeatedly until...
