You are given two strings s and t of the same length and an integer maxCost.

\n\n

You want to change s to t. Changing the ith character of s to ith character of t costs |s[i] - t[i]| (i.e., the absolute difference between the ASCII values of the characters).

\n\n

Return the maximum length of a substring of s that can be changed to be the same as the corresponding substring of t with 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.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "abcd", t = "bcdf", maxCost = 3\nOutput: 3\nExplanation: "abc" of s can change to "bcd".\nThat costs 3, so the maximum length is 3.\n
\n\n

Example 2:

\n\n
\nInput: s = "abcd", t = "cdef", maxCost = 3\nOutput: 1\nExplanation: Each character in s costs 2 to change to character in t,  so the maximum length is 1.\n
\n\n

Example 3:

\n\n
\nInput: s = "abcd", t = "acde", maxCost = 0\nOutput: 1\nExplanation: You cannot make any change, so the maximum length is 1.\n
