Thanks ! I appreciate your help . The course is about the basic principles of Programming in java and we are using the following book The question was easy but it took us the 13 of the exam time to solve it . It was to compare 2 programs and say whether they produce the same result . My main problem with the course is that i find it difficult to develop my algorithm thinking . For example when am trying to solve a problem or an assignment i reach to a point and then i don ' t know how to continue , i cannot express my think algorithmically i think . <| sep |> I have 25 hours and am not there . I have 10 about 10 champs there and the rest I don ' t like very much . My idea is to find the ones that are the most fun done and get comfortable with the viableneeded ones . My ying is decent , among the filthy casuals , but that ' s the only character I feel is ready for competitive she ' s level 9 . However , if I had done my best to just grab some experience I have no doubt I ' d be there by now .
