Given three numbers a, b and c. Write a program to swap them circularly
(as per following example) using only one single statement in any
programming language.
Ex. a=10 b=20 c=30
Answer a=20 b=30 c=10
Ex. a=10 b=20 c=30
Answer a=20 b=30 c=10
Solution :
a = a^b^c^(b=c)^(c=a);
This is equivalent to a = (a^b^c^c^a) = b along with the values of b and c being changed by b=c and c=a assignments.
This is an excellent answer and defeats the proposed ones in the reference.
