Bubble sort is a sorting algo that repeatedly steps through the list to be sorted, compares each pair of adjacent items and swaps them if they are in the wrong order.
It is a popular, but inefficient sorting algo, it has worst-case and average complexity both О(n2), where n is the number of items being sorted.
Here is an implementation in python
count = len(B) for i in xrange(count): for j in xrange(count-1,i,-1): #print "compairing %i with %i"%(B[j],B[j-1]) if B[j] < B[j - 1]: temp = B[j] B[j] = B[j - 1] B[j - 1] = temp #print "Swapping %i with %i"%(B[j],B[j-1]) #print "Transformed Array: " , B B = [6,5,3,1,8,7,2,4] print "Unsorted: ", B bubbleSort(B) print "Bubble Sorted: ", B
Hope this helps
