- * 1297. Maximum Number of Occurrences of a Substring
- *
- * Given a string s, return the maximum number of ocurrences of any substring under the following rules:
- *
- * The number of unique characters in the substring must be less than or equal to maxLetters.
- * The substring size must be between minSize and maxSize inclusive.
- *
- * Example 1:
- * Input: s = "aababcaab", maxLetters = 2, minSize = 3, maxSize = 4
- * Output: 2
- * Explanation: Substring "aab" has 2 ocurrences in the original string.
- * It satisfies the conditions, 2 unique letters and size 3 (between minSize and maxSize).
- *
- * Example 2:
- * Input: s = "aaaa", maxLetters = 1, minSize = 3, maxSize = 3
- * Output: 2
- * Explanation: Substring "aaa" occur 2 times in the string. It can overlap.
- *
- * Example 3:
- * Input: s = "aabcabcab", maxLetters = 2, minSize = 2, maxSize = 3
- * Output: 3
- *
- * Example 4:
- * Input: s = "abcde", maxLetters = 2, minSize = 3, maxSize = 3
- * Output: 0
- *
- * Constraints:
- * 1 <= s.length <= 10^5
- * 1 <= maxLetters <= 26
- * 1 <= minSize <= maxSize <= min(26, s.length)
- * s only contains lowercase English letters.
