the contest started, two problems foreach member, i got A&B, kamal C&D, moussa E&F
we solved B, as it's LCS algorithm, that's code is ready,,, but as non-expected -> WA
after some trials....WA too!!!!!!!
after few minutes, we found A solved by almost all teams, i read it again and again, kanet dema3'y me2affela, finally i got how to solve it O(n^2) {it has an easier solution O(n), e7l ma gatsh TLE}
solved the problem, submit,,,,WA!!!!!!!!!!!!!
making some modifications + submittions = WA !
kamal wrote code for his problem (C or D i don't remember)...then moussa sat to write his code, coming out silly problems!
the progress of Wael team is all what are trying to leeead, they solved about 2 problems till now! and we ZERO!
after fixing the silly problems concerning I/O with moussa's problem, we got it, the first ACCEPTED,,,,time left:= about 2 Hrs!
i'm sure of my code, for both problems, but i started getting hesitated!...i read it more than once, moussa doing so with me (As he 2affel 7'las)...kamal is fixing his code (moussa m3ah bardo :D)
{i've read kamal problem, and seen his code, and he has seen my code,,, but we didn't make big change :D....but that should happen in most cases ;) }

ignoring my sort function in both problems, the code is working correctly, i've made the sort function completely WRONG, it's returning BOOLEAN!!!!...i've fixed the problem, expecting that i'll get WA as usual :S....the second AC :D..fixed the other problem...3rd ACCEPTED, when was that...it was in the last 'freeze' hour ;)

kamal sat again to modify his problem, .................... ALLAH AKBAR that what he said, and we repeated, after he got the ACCEPTED...now 4 problems ACCEPTED.
We started solving another problems, and we are sure we won't complete it :D...but we have to do smg ;)

El salamo 3alikom wa ra7mato Allah,

about ur opinion "all te-reado el problems kolaha, then kol wa7ed yeshof emkaneyato",,, i think it won't differ if each team member knows what others know :)

that's the goal of individual contests, we don't want to break teams...we just want to improve their skills in solving problems...along with making Team-Oriented Contests too isA :D

i wish everything goes fine, to leave a big acmascis student chapter after graduate :)
Yaaa Rabb, sheddo 7elko m3ana, don't ask how :D

yalla b2a, salaaaaaam

Asmaa Magdi يقول...

7ader hashed 7ely, bass how ??!! :P

m3lesh mafhemtesh el 7etta beta3et "that's the goal of individual contests, we don't want to break teams"

eh howa el goal of indiv contests ??

Mohammed A.Aziz يقول...

"...if each team member knows what others know"

That will minimize the time of exchanging problems,
and each one in the team will be sure that others can solve what he can solve...when the other cann't, then he asks for help.
can u imagine time wasted when we all read all problems...what if i read just two problems or three, then choose the easiest to solve, while another is solving another problem on paper.

i'll manage a topic later concerning team management isA to discuss more widely our opinions.

I wish it's now more clear :)
