# [647. Palindromic Substrings](https://leetcode.com/problems/palindromic-substrings/)
|
||||
|
||||
|
||||
## 题目
|
||||
|
||||
Given a string, your task is to count how many palindromic substrings in this string.
|
||||
|
||||
The substrings with different start indexes or end indexes are counted as different substrings even they consist of same characters.
|
||||
|
||||
**Example 1:**
|
||||
|
||||
```
|
||||
Input: "abc"
|
||||
Output: 3
|
||||
Explanation: Three palindromic strings: "a", "b", "c".
|
||||
```
|
||||
|
||||
**Example 2:**
|
||||
|
||||
```
|
||||
Input: "aaa"
|
||||
Output: 6
|
||||
Explanation: Six palindromic strings: "a", "a", "a", "aa", "aa", "aaa".
|
||||
```
|
||||
|
||||
**Note:**
|
||||
|
||||
1. The input string length won't exceed 1000.
|
||||
|
||||
## 题目大意
|
||||
|
||||
给定一个字符串，你的任务是计算这个字符串中有多少个回文子串。具有不同开始位置或结束位置的子串，即使是由相同的字符组成，也会被视作不同的子串。
|
||||
|
||||
## 解题思路
|
||||
|
||||
- 暴力解法，从左往右扫一遍字符串，以每个字符做轴，用中心扩散法，依次遍历计数回文子串。
