[2015-10-26] Challenge #238 [Easy] Consonants and Vowels : dailyprogrammer
You were hired to create words for a new language. However, your boss wants these words to follow a strict pattern of consonants and vowels. You are bad at creating words by yourself, so you decide it would be best to randomly generate them.
Your task is to create a program that generates a random word given a pattern of consonants (c) and vowels (v).
String consonants = "bcdfghjklmnpqrstvwxyz";
String vowels = "aeiou";
for (char c : args[0].toCharArray()) {
char out;
switch (c) {
case 'C': out = (char)(randomSelect(consonants) - 32); break;
case 'c': out = randomSelect(consonants); break;
case 'V': out = (char)(randomSelect(vowels) - 32); break;
case 'v': out = randomSelect(vowels); break;
default: throw new RuntimeException("Input must consist of "
+ "vVcC only.");
}
System.out.print(out);
}
}
// Returns a random character in a given String.
public static char randomSelect(String s) {
return s.charAt(rng.nextInt(s.length()));
}
Scala
def rand_choice(l:List[Char]): Char = {
val rnd = new java.util.Random()
l(rnd.nextInt(l.length))
}
val vowels = "aeiouy".toList
val consanants = "bcdfghjklmnpqrstvwxz".toList
def solve(s:String): String = {
def repl(c:Char): Char = {
c match {
case 'c' => rand_choice(consanants)
case 'v' => rand_choice(vowels)
case 'C' => rand_choice(consanants).toString.toUpperCase.charAt(0)
case 'V' => rand_choice(vowels).toString.toUpperCase.charAt(0)
}
}
s.toList.map(repl).mkString
}

Your task is to create a program that generates a random word given a pattern of consonants (c) and vowels (v).
Input Description
Any string of the letters c and v, uppercase or lowercase.Output Description
A random lowercase string of letters in which consonants (bcdfghjklmnpqrstvwxyz) occupy the given 'c' indices and vowels (aeiou) occupy the given 'v' indices.Sample Inputs
