+# 画解算法：9. 回文数
+
+## 题目链接
+
+https://leetcode-cn.com/problems/palindrome-number/
+
+## 题目描述
+
+判断一个整数是否是回文数。回文数是指正序（从左向右）和倒序（从右向左）读都是一样的整数。
+
+示例 1:
+
+```bash
+输入: 121
+输出: true
+```
+
+示例 2:
+
+```bash
+输入: -121
+输出: false
+解释: 从左向右读, 为 -121 。 从右向左读, 为 121- 。因此它不是一个回文数。
+```
+
+示例 3:
+
+```bash
+输入: 10
+输出: false
+解释: 从右向左读, 为 01 。因此它不是一个回文数。
+```
+
+## 解题方案
+
+### 思路
+
+- 标签：数学
+- 如果是负数则一定不是回文数，直接返回false
+- 如果是正数，则将其倒序数值计算出来，然后比较和原数值是否相等
+- 如果是回文数则相等返回true，如果不是则不相等false
+- 比如123的倒序321，不相等；121的倒序121，相等
+
+### 代码
+
+```java
+class Solution {
+    public boolean isPalindrome(int x) {
+        if(x < 0)
+            return false;
+        int cur = 0;
+        int num = x;
+        while(num != 0) {
+            cur = cur * 10 + num % 10;
+            num /= 10;
+        }
+        return cur == x;
+    }
+}
+```
