As I thought I was done with publishing my solutions to the entire Coding Bat: Java library of exercises, with a total of over 200, Nick Parlante updated his website and added some more exercises. Apparently, his aim was to thoroughly prepare students for “FizzBuzz” interview questions.

The first exercise was added to Warmup-1, the others to Logic-1.

All solutions were successfully tested on 28 March 2013.

or35:

public boolean or35(int n) {
	return n % 3 == 0 || n % 5 == 0;
}

more20:

public boolean more20(int n) {
	return n % 20 == 1 || n % 20 == 2;
}

old35:

public boolean old35(int n) {
	return n % 3 == 0 ^ n % 5 == 0;
}

specialEleven:

public boolean specialEleven(int n) {
	return n % 11 == 0 || n % 11 == 1;
}

less20:

public boolean less20(int n) {
	return (n + 1) % 20 == 0 || (n + 2) % 20 == 0;
}

fizzString:

public String fizzString(String str) {
	boolean fizz = str.charAt(0) == 'f';
	boolean buzz = str.charAt(str.length() - 1) == 'b';

	if (fizz && buzz) return "FizzBuzz";
	if (fizz) return "Fizz";
	if (buzz) return "Buzz";
	return str;
}

fizzString2:

public String fizzString2(int n) {
	boolean fizz = n % 3 == 0;
	boolean buzz = n % 5 == 0;

	if (fizz && buzz) return "FizzBuzz!";
	if (fizz) return "Fizz!";
	if (buzz) return "Buzz!";
	return n + "!";
}
