Examples
s = "eleetminicoworoep"13The longest substring is "leetminicowor" which contains two each of the vowels: e, i and o and zero of the vowels: a and u.
s = "leetcodeisgreat"5The longest substring is "leetc" which contains two e's.
s = "bcbcbc"6In this case, the given string "bcbcbc" is the longest because all vowels: a, e, i, o and u appear zero times.
Constraints
1 <= s.length <= 5 x 10^5s contains only lowercase English letters.How Interview Coder Helps with Leetcode Problems
