_________________________
Changing value of two variables without using third variable.

Plebs:
a = a + b
b = a - b
a = a - b

Python:
a,b = b,a

@succ 👌

NumberSwitcherFactoryBuilder nsfb = new NumberSwitcherFactoryBuilder();
private volatile int firstSwitchedNumber = 0;
private volatile int secondSwitchedNumber = 1;
NumberSwitcherFactory nsf = nsfb.build(firstSwitchedNumber, secondSwitchedNumber);
nsf.produce().reverse().run();

My thumbs hurt

@BindView 😅

@succ that dayum python:)))

XCHG AL, AH

a++;
b++;

(you said change, not switch, who cares about what the client wanted when you can give them exactly what they asked for?)

@Christine shame I can only ++ your comment once! :D

Js, es6:
[a, b] = [b, a]

@succ

Damn I was gonna come in with the Python but you beat me too it.

a, b = b, a

@succ,
a=a*b
b=a/b
a=a/b

a ^= b ^= a ^= b

😎

@Christine 🤔🤐

Task said change, not switch:
a = 6;
b = "hello";

Works regardless of initial values.

@mzeffect Unless those initial values were strongly typed!
