Explanation:

501{…}fI is basically for(int I=0; I&lt;501; ++I) {…}
3s converts 3 to string, i.e. "3"
I3% is I % 3
&lt; gets the left substring - "3".substring(0, I % 3) - which is "" for I % 3 == 0 and "3" otherwise
Is converts I to string
- with 2 strings does a set difference, resulting in an empty string iff I % 3 == 0 (the first string was empty) or I has a 3 digit in it
…I"bzzt"? is like … ? I : "bzzt"; the previous string is treated as a boolean value, where "" is false and any other string is true
N adds a newline
