Given the string s, return the size of the longest substring containing each vowel an even number of times. That is, ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’ must appear an even number of times. Example 1: Input: s = "eleetminicoworoep" Output: 13 Explanation: The longest substr...
Given an array nums of integers, return how many of them contain an even number of digits. Example 1: Input: nums = [12,345,2,6,7896] Output: 2 Explanation: 12 contains 2 digits (even number of digits). 345 contains 3 digits (odd number of digits). 2 contains 1 digit (odd numbe...
1. For a given substring, we only care if all of its vowel counts are even. 2. Each time we process a new vowel character C, its count parity flips. 3. Even - Even = Even; Odd - Odd = Odd; Even - Odd = Odd; Odd - Even = Odd. Using the above observations, we derive the...
