Swap Three Numbers In Single Statement

Question

Is there any possiblty to swap three numbers in a single statement

Eg :

• a = 10
• b = 20
• c = 30

I want values to be changed as per the following list

a = 20
b = 30
c = 10

Can these values be transferred in a single line?

Answer 1

$ python
>>> a, b, c = 10, 20, 30
>>> print a, b, c
10 20 30
>>> a, b, c = b, c, a
>>> print a, b, c
20 30 10

Answer 2

I found another solution for this question.

You can use this in many languages like C,C++ and Java.

It will work for float and long also.

a=(a+b+c) - (b=c) - (c=a);
