Dear Solo friends, could anyone explain me the output of this code, please?
int[] a = {1, 2, 3, 4, 1}; for(int n:a) a[n]=0; for(int n:a) System.out.println(n); The output is 00301 I thought, that the answer is 00000, but it is wrong.

Xan thankyou very much for your answer Xan. It makes sense for me now 🙄
Talking about braces and identations, I try to use them whenever possible because I find the code without them less readable, too. It's just a code from a challenge question and I didn't want to change anything in it.
thankyou again!

Always put debug output in your code to find problems:

Your first for loop is doing this:
a[1] = 0;
a[0] = 0;
a[3] = 0;
a[0] = 0;
a[1] = 0;
Meaning a[2] and a[4] remain unchanged.
Also, always use braces, and identation. It won't slow down the execution of code, and it's a lot more readable.
