why all the editorial are in C language … can anyone write the editorials in java plzz?
I think you mean code in JAVA. Editorials are written in English
If you want code in JAVA most of the problems have JAVA submissions at the end of the list of Accepted solutions for the problem.
You can go through them I guess.
You can find some top contestants(like EgorK) who code in JAVA, if they participate in a contest, they solve the whole problem set(more often than not) you can check their profiles for JAVA implementations.
why all the editorial are in C language
Code are submitted in the language one is comfortable in. And C or C++ (as visible on problem pages) happen to be quite popular, so they are mostly in C or C++.
But is this a problem, for say a Java programmer?
No. Because the code in any language (baring the esoteric one’s) is supposed to be written, so that it could be understood easily. And with a good editorial, code becomes even simpler to comprehend.
To understand the logic of the solution, any common programming language is sufficient.
One can easily write his/her own versions of the solution in any language of his/her own choice, once the idea is clear.
