Problem Statement for "VowelEncryptor"

Problem Statement

You are given a String[] text, each element of which contains a single word. Encrypt the text by removing all vowels ('a', 'e', 'i', 'o', 'u') from every word that contains at least one non-vowel. If a word consists only of vowels, leave it as is. Return the result as a String[], where the ith element is the encrypted version of the ith element in text.

Definition

Class:
VowelEncryptor
Method:
encrypt
Parameters:
String[]
Returns:
String[]
Method signature:
String[] encrypt(String[] text)
(be sure your method is public)

Constraints

  • text will contain between 1 and 50 elements, inclusive.
  • Each element of text will contain between 1 and 20 lowercase letters ('a'-'z'), inclusive.

Examples

  1. {"hello", "world"}

    Returns: {"hll", "wrld" }

  2. {"a", "b", "c"}

    Returns: {"a", "b", "c" }

  3. {"he", "who", "is", "greedy", "is", "disgraced"}

    Returns: {"h", "wh", "s", "grdy", "s", "dsgrcd" }

  4. {"aaaaaaaaaaaaaaaaaaaa","ooooooooooooooooooop"}

    Returns: {"aaaaaaaaaaaaaaaaaaaa", "p" }

  5. {"alkjhvicou", "xwqerqwed", "xcmhlksjr", "qwerosdibm", "ponkldfsgjer"}

    Returns: {"lkjhvc", "xwqrqwd", "xcmhlksjr", "qwrsdbm", "pnkldfsgjr" }

  6. {"kv", "gy", "ab", "yd", "qz", "it", "dv", "kr", "tr", "eu", "jt", "wm", "xi", "ek", "bx", "dh", "pf", "qz", "zl", "co", "ka", "eo", "dc", "qx", "hj", "su", "ov", "xd", "pl", "dd", "dm", "eb", "gx", "ew", "oe", "kl", "zt", "te", "cl", "te", "lz", "um", "xt", "wt", "me", "ni", "rm", "hd", "xc", "bq"}

    Returns: {"kv", "gy", "b", "yd", "qz", "t", "dv", "kr", "tr", "eu", "jt", "wm", "x", "k", "bx", "dh", "pf", "qz", "zl", "c", "k", "eo", "dc", "qx", "hj", "s", "v", "xd", "pl", "dd", "dm", "b", "gx", "w", "oe", "kl", "zt", "t", "cl", "t", "lz", "m", "xt", "wt", "m", "n", "rm", "hd", "xc", "bq" }

    This should test whether a solution correctly defines which letter is a vowel and which is not. For a pair of letters among which one is a vowel and other isn't, the vowel should be excluded. Otherwise, both letters are kept. Since we can't create a test with 26*26 letter pairs, I added several tests with random pairs.

  7. {"ki", "vz", "ug", "mo", "zv", "kb", "dn", "rb", "pw", "ev", "zh", "ty", "bl", "mo", "pe", "cb", "ve", "zm", "ve", "fz", "ug", "tc", "og", "bc", "wk", "bo", "yu", "zh", "rn", "ox", "zo", "tu", "gj", "nf", "nu", "jc", "gl", "wk", "ug", "kf", "ly", "pw", "eq", "vl", "km", "dl", "xb", "bz", "zq", "cx"}
