# 1119. Remove Vowels from a String

Given a string `S`, remove the vowels `'a'`, `'e'`, `'i'`, `'o'`, and `'u'` from it, and return the new string.

**Example 1:**

```
Input: "leetcodeisacommunityforcoders"
Output: "ltcdscmmntyfrcdrs"
```

**Example 2:**

```
Input: "aeiou"
Output: ""
```

**Note:**

1. `S` consists of lowercase English letters only.
2. `1 <= S.length <= 1000`

```cpp
string removeVowels(string S) { // time: O(n); space: O(n)
    if (S.empty()) return S;
    int n = S.length();
    string vowels = "aeiouAEIOU", res;
    for (int i = 0 ; i < n; ++i) {
        if (vowels.find(S[i]) == string::npos) res += S[i];
    }
    return res;
}
```
