 ## Description
+You are given two strings `sentence1` and `sentence2`, each representing a **sentence** composed of **words**. A sentence is a list of words that are separated by a **single** space with no leading or trailing spaces. Each word consists of only uppercase and lowercase English characters.
+
+Two sentences `s1` and `s2` are considered **similar** if it is possible to insert an arbitrary sentence (possibly empty) inside one of these sentences such that the two sentences become equal. **Note** that the inserted sentence must be separated from existing words by spaces.
+
+For example,
+
+- `s1 = "Hello Jane"` and `s2 = "Hello my name is Jane"` can be made equal by inserting `"my name is"` between `"Hello"` and `"Jane"` in s1.
+- `s1 = "Frog cool"` and `s2 = "Frogs are cool"` are **not** similar, since although there is a sentence `"s are"` inserted into `s1`, it is not separated from `"Frog"` by a space.
+
+Given two sentences `sentence1` and `sentence2`, return **true** if `sentence1` and `sentence2` are **similar**. Otherwise, return **false**.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
+Input: sentence1 = "My name is Haley", sentence2 = "My Haley"
+
+Output: true
+
+Explanation:
+
+sentence2 can be turned to sentence1 by inserting "name is" between "My" and "Haley".
 ```

+**Example 2:**
 
-## 题解
+```
+Input: sentence1 = "of", sentence2 = "A lot of words"
+
+Output: false
+
+Explanation:
+
+No single sentence can be inserted inside one of the sentences to make it equal to the other.
+```
+
+**Example 3:**
 
-### 思路1
-> ...
-Sentence Similarity III
-```go
 ```
+Input: sentence1 = "Eating right now", sentence2 = "Eating"
+
+Output: true
 
+Explanation:
+
+sentence2 can be turned to sentence1 by inserting "right now" at the end of the sentence.
+```
