+# [1408.String Matching in an Array][title]
+
+## Description
+Given an array of string `words`, return all strings in `words` that is a **substring** of another word. You can return the answer in **any order**.
+
+A **substring** is a contiguous sequence of characters within a strings
+
+**Example 1:**
+
+```
+Input: words = ["mass","as","hero","superhero"]
+Output: ["as","hero"]
+Explanation: "as" is substring of "mass" and "hero" is substring of "superhero".
+["hero","as"] is also a valid answer.
+```
+
+**Example 2:**
+
+```
+Input: words = ["leetcode","et","code"]
+Output: ["et","code"]
+Explanation: "et", "code" are substring of "leetcode".
+```
+
+**Example 3:**
+
+```
+Input: words = ["blue","green","bu"]
+Output: []
+Explanation: No string of words is substring of another string.
+```
