contains both of these characters. For k = 2, the longest substring of s that contains at most k = 2 normal characters is 5 characters long, abcde, so the return value is 5. If k = 1 instead, then the possible

character is normal is determined by a 26- digit bit string named charValue. Each digit in charValue corresponds to a lowercase letter in the English alphabet. Example: s = 'abcde' alphabet = abcdefghijklmnopqrstuvwxyz charValue = 1010111111111111 1111 For clarity, the alphabet is aligned with charValue

. Intelligent Substring There are two types of characters in a particular language: special and normal. A character is special if its value is 1 and normal if its value is 0. Given string s, return the longest
