You are given a string s consisting of lowercase English letters, and an integer k. Your task is to convert the string into an integer by a special process, and then transform it by summing its digits repeatedly k times. More specifically, perform the following steps:
s into an integer by replacing each letter with its position in the alphabet (i.e. replace 'a' with 1, 'b' with 2, ..., 'z' with 26).k times in total.For example, if s = "zbax" and k = 2, then the resulting integer would be 8 by the following operations:
"zbax" ➝ "(26)(2)(1)(24)" ➝ "262124" ➝ 262124262124 ➝ 2 + 6 + 2 + 1 + 2 + 4 ➝ 1717 ➝ 1 + 7 ➝ 8Return the resulting integer after performing the operations described above.
\n\n\n
Example 1:
\n\nInput: s = "iiii", k = 1
\n\nOutput: 36
\n\nExplanation:
\n\nThe operations are as follows:
\n- Convert: "iiii" ➝ "(9)(9)(9)(9)" ➝ "9999" ➝ 9999
\n- Transform #1: 9999 ➝ 9 + 9 + 9 + 9 ➝ 36
\nThus the resulting integer is 36.
Example 2:
\n\nInput: s = "leetcode", k = 2
\n\nOutput: 6
\n\nExplanation:
\n\nThe operations are as follows:
\n- Convert: "leetcode" ➝ "(12)(5)(5)(20)(3)(15)(4)(5)" ➝ "12552031545" ➝ 12552031545
\n- Transform #1: 12552031545 ➝ 1 + 2 + 5 + 5 + 2 + 0 + 3 + 1 + 5 + 4 + 5 ➝ 33
\n- Transform #2: 33 ➝ 3 + 3 ➝ 6
\nThus the resulting integer is 6.
Example 3:
\n\nInput: s = "zbax", k = 2
\n\nOutput: 8

Constraints:
\n\n1 <= s.length <= 1001 <= k <= 10s consists of lowercase English letters.给你一个由小写字母组成的字符串 s ，以及一个整数 k 。你的任务是通过一种特殊处理将字符串转为整数，然后通过重复对它的数位求和 k 次来进行转换。更具体地说，执行以下步骤：
s 转化 为一个整数（也就是，'a' 用 1 替换，'b' 用 2 替换，... 'z' 用 26 替换）。k 次 。例如，如果 s = \"zbax\" 且 k = 2 ，那么执行下述步骤后得到的结果是整数 8 ：
\"zbax\" ➝ \"(26)(2)(1)(24)\" ➝ \"262124\" ➝ 262124262124 ➝ 2 + 6 + 2 + 1 + 2 + 4 ➝ 1717 ➝ 1 + 7 ➝ 8返回执行上述 操作 后得到的 结果整数。

示例 1：
\n\n示例 2：
\n\n因此，结果整数为 6 。

示例 3：
\n\n输入：s = \"zbax\", k = 2
\n\n输出：8
