1208. Get Equal Substrings Within Budget
https://leetcode.com/problems/get-equal-substrings-within-budget
Description
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 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
.
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
andt
only contain lower case English letters.
