Thanksss!!! It is working. my solution is ACCEPTED by changing 100*tab[i]; by 100*tab[i]+0.5;
I should be more careful now with the type double.... To submit your code you should register to UVA website. Then you go on this link (The link of the problem) http://uva.onlinejudge.org/index.php?option=com_onlinejudge&Itemid=8&category=29&page=show_problem&problem=1078 Then you click Submit Button (on top of the problem). You choose your language (Java). You can paste your code or Click Browse to load the source file and then click Submit. you will receive an email to see the results or you can go to MySubmissions ( menu on the left side ).
