Example 2:
Input: "aeiou"

Note:
S consists of lowercase English letters only.1 <= S.length <= 1000
class Solution { public String removeVowels(String S) { Set<Character> set = new HashSet<>(); set.add(‘a‘); set.add(‘e‘); set.add(‘i‘); set.add(‘o‘); set.add(‘u‘); char[] chs = S.toCharArray(); int i = 0, j = 0; while(j < chs.length) { if(set.contains(chs[j])) { j++; } else { chs[i++] = chs[j++]; } } return new String(chs, 0, i); } }
