You are given a string s of lowercase English letters and a 2D integer array shifts where shifts[i] = [starti, endi, directioni]. For every i, shift the characters in s from the index starti to the index endi (inclusive) forward if directioni = 1, or shift the characters backward if directioni = 0.
Shifting a character forward means replacing it with the next letter in the alphabet (wrapping around so that 'z' becomes 'a'). Similarly, shifting a character backward means replacing it with the previous letter in the alphabet (wrapping around so that 'a' becomes 'z').
Return the final string after all such shifts to s are applied.
\n
Example 1:
\n\n\nInput: s = "abc", shifts = [[0,1,0],[1,2,1],[0,2,1]]\nOutput: "ace"\nExplanation: Firstly, shift the characters from index 0 to index 1 backward. Now s = "zac".\nSecondly, shift the characters from index 1 to index 2 forward. Now s = "zbd".\nFinally, shift the characters from index 0 to index 2 forward. Now s = "ace".\n\n
Example 2:
\n\n\nInput: s = "dztz", shifts = [[0,0,0],[1,1,1]]\nOutput: "catz"\nExplanation: Firstly, shift the characters from index 0 to index 0 backward. Now s = "cztz".\nFinally, shift the characters from index 1 to index 1 forward. Now s = "catz".\n\n\n
\n
Constraints:
\n\n1 <= s.length, shifts.length <= 5 * 104shifts[i].length == 30 <= starti <= endi < s.length0 <= directioni <= 1s consists of lowercase English letters.给你一个小写英文字母组成的字符串 s 和一个二维整数数组 shifts ，其中 shifts[i] = [starti, endi, directioni] 。对于每个 i ，将 s 中从下标 starti 到下标 endi （两者都包含）所有字符都进行移位运算，如果 directioni = 1 将字符向后移位，如果 directioni = 0 将字符向前移位。
将一个字符 向后 移位的意思是将这个字符用字母表中 下一个 字母替换（字母表视为环绕的，所以 'z' 变成 'a'）。类似的，将一个字符 向前 移位的意思是将这个字符用字母表中 前一个 字母替换（字母表是环绕的，所以 'a' 变成 'z' ）。
请你返回对 s 进行所有移位操作以后得到的最终字符串。
\n\n
示例 1：
\n\n输入：s = \"abc\", shifts = [[0,1,0],[1,2,1],[0,2,1]]\n输出：\"ace\"\n解释：首先，将下标从 0 到 1 的字母向前移位，得到 s = \"zac\" 。\n然后，将下标从 1 到 2 的字母向后移位，得到 s = \"zbd\" 。\n最后，将下标从 0 到 2 的字符向后移位，得到 s = \"ace\" 。\n\n
示例 2:
\n\n输入：s = \"dztz\", shifts = [[0,0,0],[1,1,1]]\n输出：\"catz\"\n解释：首先，将下标从 0 到 0 的字母向前移位，得到 s = \"cztz\" 。\n最后，将下标从 1 到 1 的字符向后移位，得到 s = \"catz\" 。\n\n\n

提示：
\n\n1 <= s.length, shifts.length <= 5 * 104shifts[i].length == 30 <= starti <= endi < s.length0 <= directioni <= 1s 只包含小写英文字母。\\u7248\\u672c\\uff1a
