You are given a string s and two integers x and y. You can perform two types of operations any number of times.
"ab" and gain x points.\n\n\t"ab" from "cabxbae" it becomes "cxbae"."ba" and gain y points.\n\t"ba" from "cabxbae" it becomes "cabxe".Return the maximum points you can gain after applying the above operations on s.
\n
Example 1:
\n\n\nInput: s = "cdbcbbaaabab", x = 4, y = 5\nOutput: 19\nExplanation:\n- Remove the "ba" underlined in "cdbcbbaaabab". Now, s = "cdbcbbaaab" and 5 points are added to the score.\n- Remove the "ab" underlined in "cdbcbbaaab". Now, s = "cdbcbbaa" and 4 points are added to the score.\n- Remove the "ba" underlined in "cdbcbbaa". Now, s = "cdbcba" and 5 points are added to the score.\n- Remove the "ba" underlined in "cdbcba". Now, s = "cdbc" and 5 points are added to the score.\nTotal score = 5 + 4 + 5 + 5 = 19.\n\n
Example 2:
\n\n\nInput: s = "aabbaaxybbaabb", x = 5, y = 4\nOutput: 20\n\n\n
\n
Constraints:
\n\n1 <= s.length <= 1051 <= x, y <= 104s consists of lowercase English letters.给你一个字符串 s 和两个整数 x 和 y 。你可以执行下面两种操作任意次。
\"ab\" 并得到 x 分。\n\n\t\"cabxbae\" 删除 ab ，得到 \"cxbae\" 。\"ba\" 并得到 y 分。\n\t\"cabxbae\" 删除 ba ，得到 \"cabxe\" 。请返回对 s 字符串执行上面操作若干次能得到的最大得分。
\n\n
示例 1：
\n\n输入：s = \"cdbcbbaaabab\", x = 4, y = 5\n输出：19\n解释：\n- 删除 \"cdbcbbaaabab\" 中加粗的 \"ba\" ，得到 s = \"cdbcbbaaab\" ，加 5 分。\n- 删除 \"cdbcbbaaab\" 中加粗的 \"ab\" ，得到 s = \"cdbcbbaa\" ，加 4 分。\n- 删除 \"cdbcbbaa\" 中加粗的 \"ba\" ，得到 s = \"cdbcba\" ，加 5 分。\n- 删除 \"cdbcba\" 中加粗的 \"ba\" ，得到 s = \"cdbc\" ，加 5 分。\n总得分为 5 + 4 + 5 + 5 = 19 。\n\n
示例 2：
\n\n输入：s = \"aabbaaxybbaabb\", x = 5, y = 4\n输出：20\n\n\n

提示：
\n\n1 <= s.length <= 1051 <= x, y <= 104s 只包含小写英文字母。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
