How do you program an in-place algorithm using a functional language?

>in-place algorithm
Why would you want that? And don't tell me for performance reasons.

>>59932921
You don't.
You'd do that for performance reasons, but some compilers can tell if something is meant to be in-place in some situations.
However, as a general rule, if you want to have both high throughput and low latency, pure functional programming isn't a good idea anyway.

Fuck off back to /tech/, this board is for the discussion of graphic cards and CPUs.

the compiler will do it for you if it is good enough
