Find relation for interact (e, DR, operateElement, dfsTimes).
| | Input: | | | element ; dependencies set DR; dependent interactive elements operateElement; time of iterations dfsTimes | | | Output: | | | operateElement | | (1) | if dfsTimes ≥ 20 | | (2) | return | | (3) | end if | | (4) | dfsTimes = dfsTimes + 1 | | (5) | if e.type = invisible | | (6) | return | | (7) | end if | | (8) | if e.type == visible&interactive&independent | | (9) | return | | (10) | end if | | (11) | if e.type == visible&interactive&dependent | | (12) | | | (13) | fordo | | (14) | if | | (15) | | | (16) | if answer ! = Null | | (17) | | | (18) | end if | | (19) | end if | | (20) | end for | | (21) | if operateElement == Null | | (22) | | | (23) | end if | | (24) | else | | (25) | return | | (26) | end if |
