AlgoDeduce

 Generator: loading...

Deduce the algorithm:
Press the Generate button a few times and try to figure out an algorithm that expresses the relation between the Input and the Expected result.
Edit and Run your Prequel program.
Test as many instances as needed with Retry while ok.

After Submit program, players may inspect and run standardized versions of other submitted programs.
Receive bonus points for revealing errors in other solutions while penalizing their Code golf rank.

Note that you can also create your own generator.

Parser Error: UNEXPECTED CHAR

Module: main

 algo.return(algo.input)

Input:

 ALGO.INPUT 
  Number or list 
   from which the expected result must be calculated 
   and returned through procedure ALGO.RETURN. 
  
 CALL.ARGS 
  Holds the list of arguments passed with CALL. 
  -> [arg1, ..., argN]

Procedures:

 ALGO.RETURN(result) 
  End computation and 
   compare the calculated result 
   against the expected result. 
  Succeeds if there is a match; fails otherwise. 
  
 CALL(&retvar1, ..., &retvarM, @modname, arg1, ..., argN) 
  Start executing module modname, copying N arguments and expecting M return values. 
  -> retvar: name of variable to hold the corresponding return value retval 
  -> modname: name of module to start executing 
  -> arg: value to be copied to the list CALL.ARGS 
  Alternative syntax: retvar1, ..., retvarM := CALL(@modname, arg1, ..., argN) 
  Note that recursive module calls are not allowed. 
  
 RETURN(retval1, ..., retvalM) 
  Return M values from the current module. 
  Resume execution at the next instruction of the corresponding CALL. 
  -> retval: value to be copied to the corresponding variable retvar
