+### 🚀 LeetCode

+
+<span style="color: #00AF9B;">**Easy**</span> [**https://leetcode.cn/problems/longest-common-prefix/**](https://leetcode.cn/problems/longest-common-prefix/)
+
+---
+
+### ❓ Description
+
+<br/>
+
+编写一个函数来查找字符串数组中的最长公共前缀。
+
+如果不存在公共前缀，返回空字符串 `""`。
+
+<br/>
+
+**示例 1：**
+
+```
+输入: strs = ["flower", "flow", "flight"]
+输出: "fl"
+```
+
+**示例 2：**
+
+```
+输入: strs = ["dog", "racecar", "car"]
+输出: ""
+解释: 输入不存在公共前缀
+```
+
+<br/>
+
+**提示：**
+
+* `1 <= strs.length <= 200`
+* `0 <= strs[i].length <= 200`
+* `strs[i]` 仅由小写英文字母组成
+
+---
+
+### ❗ Solution
+
+<br/>
+
+#### Java
+
+```
+class Solution {
+    public String longestCommonPrefix(String[] strs) {
+        if (strs.length == 1) {
+            return strs[0];
+        }
+
+        int length = Integer.MAX_VALUE;
+        for (String str : strs) {
+            length = Math.min(length, str.length());
+        }
+
+        StringBuilder result = new StringBuilder();
+        boolean end = false;
+
+        for (int i = 0; i < length; i++) {
+            Character c = strs[0].charAt(i);
+            for (int j = 1; j < strs.length; j++) {
+                if (!c.equals(strs[j].charAt(i))) {
+                    end = true;
+                    break;
+                }
+            }
+            if (end) {
+                break;
+            } else {
+                result.append(c);
+            }
+        }
+        return result.toString();
+    }
+}
+```
