little algorithm riddle

[Michael_Keller1]

Dear community, a little bit of fun today. I recently saw an algorithm that really surprised me by his effectivity. Mankind has known this algorithm for some time. I tried an implementation in ABAP out of interest. I hope the implementation works 😉 What is the name?

I put the answer in mirror writing under the source code. Hold a mirror to your screen. Instead of a mirror a smartphone screen is sufficient to "decode", too 🙂

If someone also has a little algorithm riddle, feel free to write a blog. If the implementation doesn't work properly, no problem. I guess there are some members here who can fix this 😉

CLASS-METHODS do_something

   IMPORTING

     x             TYPE i

     y             TYPE i

   RETURNING

     VALUE(result) TYPE i.

[..]

METHOD do_something.

  IF x = 1.

    result = y.

  ELSE.

    IF x MOD 2 > 0.

      result = y + do_something( x = x DIV 2

                                 y = y + y ).

    ELSE.

      result = do_something( x = x DIV 2

                             y = y + y ).

    ENDIF.

  ENDIF.

ENDMETHOD.

Here ist the answer:
