You are given two strings s and t of the same length. You want to change s to t. Changing the i-th character of s to i-th character of t costs |s[i] - t[i]| that is, the absolute difference between the ASCII values of the characters. You are also given an integer maxCost. Return the maximum length of a substring of s that can be changed to be the same as the corresponding substring of twith a cost less than or equal to maxCost. If there is no substring from s that can be changed to its corresponding substring from t, return 0. Example 1: Input: s = "abcd", t = "bcdf", maxCost = 3 Output: 3 Explanation: "abc" of s can change to "bcd". That costs 3, so the maximum length is 3. Example 2: Input: s = "abcd", t = "cdef", maxCost = 3 Output: 1 Explanation: Each character in s costs 2 to change to charactor in t, so the maximum length is 1. Example 3: Input: s = "abcd", t = "acde", maxCost = 0 Output: 1 Explanation: You can't make any change, so the maximum length is 1. Constraints: 1 <= s.length, t.length <= 10^5 0 <= maxCost <= 10^6 s and t only contain lower case English letters.
