I'm still new to the while includes method
Whole*
"okay, the callback runs. 1 is used as the value in that function (element)."
"the callback wants to know if !args.includes(element), so does the args array NOT include this element (1)?"
just as
function foo(a) {return a;} doesn't need a to be declared
Just keep practicing and asking questions
package addchain;
import java.util.*;
public class reeer {
public static void main(String[] args) {
int chainLength = Integer.parseInt(args[0]) + 1;
int chainTarget = Integer.parseInt(args[1]);
Random rng = new Random();
List<Integer> chain = new ArrayList<>();
chain.add(1);
while (true) {
while (chain.size() != chainLength)
chain.add(chain.get(rng.nextInt(chain.size())) + chain.get(chain.size() - 1));
if (chain.get(chain.size() - 1) == chainTarget) {
System.out.println(chain);
break;
}
chain.clear();
chain.add(1);
}
}
}
i am getting this error
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

*URGENT
@TonyRednil practice running through those steps and talking through each arr[0] and then arr[1] kinda like i started to show you
Ooh, @Devansh-Anhal , I don't really know Java at all but I'll try to help
@Devansh-Anhal , you do realize this is a front-end help chat room? (HTML, CSS, JS)
i am really sorry
@Devansh-Anhal https://stackoverflow.com/questions/17570003/error-in-arrayindexoutofboundsexception-0 << does that help?
Have a few Js doubts, im submitting some code for an interview, and some questions came up regarding style which i
d like to talk over if anyone's around :D
im just not sure about some things that i know work, but wonder if its the correct way to write it :/
like maybe im overextracting stuff into functions. i try not to compromise legibility and "ease of following wtf is going on"
but then again, DRY stabs me in the face and i HAVE to avoid repeating stuff :D
all in all im not satisfied that the implementation works, but i'd like the code to look nice... despite the fact they know i havent worked more than a few freelance projects (and you pretty much make up the rules as you go there)
otherwise the general stuff should be ok. Idk if you code looks like a mess so idk past that
mayhaps just need to vent it out a bit and then click the send button with what i've got :D
function a(){
functionb()
functionc()
functiond()
}
i just feel that is dirty for some reason
but it does help me handle an event on the browser in multiple places, by using a() and keeping each eventhandler short
were talking about vanillajs right? Opens up alot of ideas on style
constraint is use no libraries, no frameworks, just vanilla
