I ran into the FizzBuzz challenge at HackerRank (https://www.hackerrank.com/challenges/fizzbuzz?h_r=internal-search).
If you are interested take a look at the specified URL.
It was interesting the following statement: Write a solution (or reduce an existing one) so it has as few characters as possible.
It seems to me that the practice of writing cryptic code should not be encouraged. That code needs to be maintained and in most cases modified. That said, given specific requirements, if needed very compact but efficient and well documented code is required in some cases.
The challenge did not provide sample input (non-existent) and the output was well described so there was no need for sample output.
The console output from the Eclipse IDE generated by my solution follows:

The following Java code passed the single test case:
public class Solution {
public static void main(String[] args) {
// **** second attempt (passed) ****
String s = “”;
for (int i = 1; i <= 100; i++) {
if (((i % 3) == 0) && ((i % 5) == 0)) {
s = “FizzBuzz”;
}
if (((i % 3) == 0) && ((i % 5) != 0)) {
s = “Fizz”;
}
if (((i % 3) != 0) && ((i % 5) == 0)) {
s = “Buzz”;
}
if (((i % 3) != 0) && ((i % 5) != 0)) {
s = Integer.toString(i);
}
System.out.println(s);
// **** first attempt (passed) ****
// if (((i % 3) == 0) && ((i % 5) == 0)) {
// System.out.println(“FizzBuzz”);
// }
// if (((i % 3) == 0) && ((i % 5) != 0)) {
// System.out.println(“Fizz“);
// }
// if (((i % 3) != 0) && ((i % 5) == 0)) {
// System.out.println(“Buzz”);
// }
// if (((i % 3) != 0) && ((i % 5) != 0)) {
// System.out.println(i);
// }
}
}
}
