 ## Description
+You are given a string `s` that consists of lower case English letters and brackets.
+
+Reverse the strings in each pair of matching parentheses, starting from the innermost one.
+
+Your result should **not** contain any brackets.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: s = "(abcd)"
+Output: "dcba"
 ```

-### 思路1
-> ...
-Reverse Substrings Between Each Pair of Parentheses
-```go
 ```
+Input: s = "(u(love)i)"
+Output: "iloveu"
+Explanation: The substring "love" is reversed first, then the whole string is reversed.
+```
+
+**Example 3:**
 
+```
+Input: s = "(ed(et(oc))el)"
+Output: "leetcode"
+Explanation: First, we reverse the substring "oc", then "etco", and finally, the whole string.
+```
