3 *
4 * A fancy string is a string where no three consecutive characters are equal.
5 * Given a string s, delete the minimum possible number of characters from s to make it fancy.
6 * Return the final string after the deletion. It can be shown that the answer will always be unique.

8 * Example 1:
9 * 
10 * Input: s = "le<u>e</u>etcode"
11 * Output: "leetcode"
12 * Explanation:
13 * Remove an 'e' from the first group of 'e's to create "leetcode".
14 * No three consecutive characters are equal, so return "leetcode".
15 * 
16 * Example 2:
17 * 
18 * Input: s = "<u>a</u>aab<u>aa</u>aa"
19 * Output: "aabaa"
20 * Explanation:
21 * Remove an 'a' from the first group of 'a's to create "aabaaaa".
22 * Remove two 'a's from the second group of 'a's to create "aabaa".
