+
+Given an encoded string, return its decoded string.
+
+The encoding rule is: `k[encoded_string]`, where the `encoded_string` inside the square brackets is being repeated exactly `k` times. Note that `k` is guaranteed to be a positive integer.
+
+You may assume that the input string is always valid; there are no extra white spaces, square brackets are well-formed, etc. Furthermore, you may assume that the original data does not contain any digits and that digits are only for those repeat numbers, `k`. For example, there will not be input like `3a` or `2[4]`.
+
+The test cases are generated so that the length of the output will never exceed `105`.
+
+**Example 1:**
+
+```
+Input: s = "3[a]2[bc]"
+Output: "aaabcbc"
+```
+
+**Example 2:**
+
+```
+Input: s = "3[a2[c]]"
+Output: "accaccacc"
+```
+
+**Example 3:**
+
+```
+Input: s = "2[abc]3[cd]ef"
+Output: "abcabccdcdcdef"
+```
+
+**Constraints:**
+
+- `1 <= s.length <= 30`
+- `s` consists of lowercase English letters, digits, and square brackets `'[]'`.
+- `s` is guaranteed to be **a valid** input.
+- All the integers in `s` are in the range `[1, 300]`.
