Unnecessary TLE in JAVA in LTime75A

help

In the the contest i had submitted my code in JAVA for Chef Drinks Coke Yet Again (COKE2)

I got a TLE in one of the subtask 2 cases in JAVA.
I copied my code in cpp, made the necessary changes, and voila!! My code gets accepted!!
I wasted about 15-20 mins converting my code to cpp, which affected my rank.
Can you please do better testing so such cases don’t happen @admin ?

Here are links to my solutions, you will find that both are DITTO same:
JAVA : https://www.codechef.com/viewsolution/26181207
CPP: https://www.codechef.com/viewsolution/26185132

maybe bcz u used fastIO in cpp and btw cpp is always faster than Java … google it why u will get whole detail

CodeChef doesn’t like Java :slight_smile:

Seriously, tuning the time limits for various languages is quite a difficult task, I don’t think there is a good solution to that.

In general, I have a feeling that switching to C++ will increase one’s productivity by roughly 20%, just because of the language change.

well everyone knows cpp is faster than java but there is a thing called time multiplier different for each language. so that algorithm which runs in cpp in unit sec can run in others languages accordingly.
PS: it might happen that time multiplier isn’t same for each problem.

Java is a favorite among developers, but because the code must first be interpreted during run-time, it’s also slower. C++ is compiled to binaries, so it runs immediately and therefore faster than Java programs. … Java does not support pointers, so you are only able to pass values using value references.

Well i used Fast IO in JAVA too. And yes, i am aware Cpp is faster, but it is the responsibility of testers that JAVA and other programmers coding in other languages don’t get unfair disadvantage due to this.

It is a very naive approximation and simplification to believe that execution time in Java can be expressed as a simple function compared to the one in C++. Whoever thinks that Time(Java) = Multiplier*Time(C++) … should basically forget about Computer Science and change their field

Yeah man…i have faced this issue on codechef many times

read my above comments again…
. for even better performance you may use brainfuck… but u know what will happen next LOL :smile:

Many people got 100 in Coke2 using java. so i think there is no Java issue…similar thing happened with me in Destroy Cells problem using java…

they want java users to optimize their code and learn new methods… so make u learn new methods… for which u shouldnt be complaining instead say thanks XD

Many people getting AC doesn’t mean the issue i faced is isn’t valid.
If the same solution in cpp gets AC then don’t you think there was an unfair disadvantage to me?

no … @vijju123 will clarify more

ur code seems optimal afik but obj creation is costly op. Hence the ‘pair’ might be the reason
also I am not sure if generics affects execution time as they are resolved in compile time

18

I am telling in this respect this is totally crap statement

19

it happens
the tester is not responsible for writing the code in every lang
do u know every lang ?
sad truth man but java is not for CP
I too use java and face this issue in CP

It depends on you/me how you code and how much knowledge you/me have about the language.
eg: better example Arrays.sort() in java…
