You are given two strings s and t.
You are allowed to remove any number of characters from the string t.
The score of the string is 0 if no characters are removed from the string t, otherwise:
left be the minimum index among all removed characters.right be the maximum index among all removed characters.Then the score of the string is right - left + 1.
Return the minimum possible score to make t a subsequence of s.
A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters. (i.e., "ace" is a subsequence of "abcde" while "aec" is not).

Example 1:
\n\n\nInput: s = "abacaba", t = "bzaa"\nOutput: 1\nExplanation: In this example, we remove the character "z" at index 1 (0-indexed).\nThe string t becomes "baa" which is a subsequence of the string "abacaba" and the score is 1 - 1 + 1 = 1.\nIt can be proven that 1 is the minimum score that we can achieve.\n\n\n
Example 2:
\n\n\nInput: s = "cde", t = "xyz"\nOutput: 3\nExplanation: In this example, we remove characters "x", "y" and "z" at indices 0, 1, and 2 (0-indexed).\nThe string t becomes "" which is a subsequence of the string "cde" and the score is 2 - 0 + 1 = 3.\nIt can be proven that 3 is the minimum score that we can achieve.\n\n\n
