# 344_Reverse_String
###### tags: `leetcode`
## Problem Statement
Write a function that reverses a string. The input string is given as an array of characters char[].

Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory.

You may assume all the characters consist of printable ascii characters.

- Example 1:

> Input: ["h","e","l","l","o"]
> Output: ["o","l","l","e","h"]
- Example 2:

> Input: ["H","a","n","n","a","h"]
> Output: ["h","a","n","n","a","H"]

## Solution
- Simply use ```reverse()``` function to reverse the string.
```cpp=
reverse(s.begin(), s.end());
```
