SpletA simple swap function in Python is generally considered a function that takes two initialized variables, a = val_a and b = val_b, and returns a result of a = val_b and b = val_a. The function accepts variables of arbitrary types, or more precisely, variables that are assigned with objects of arbitrary types. SpletStep 1: A = arr [0...1] = [1,2] & B = arr [2...4] = [3,4,5] Step 2 : As Size (A) < Size (B), swap A with B2 where B2 = [4,5] & B1 = [3]. So, A = [B2] = [4,5] and B = [B1] [A] = [3,1,2]. Now, continue for [4,5,3] which corresponds to [B2] [B1] as [A] is at it's final position. So, for the next iteration, the arr is [4,5,3], N = 5, d = 2.
