# [1189. Maximum Number of Balloons](https://leetcode.com/problems/maximum-number-of-balloons/)
## 题目:
Given a string `text`, you want to use the characters of `text` to form as many instances of the word **"balloon"** as possible.
You can use each character in `text` **at most once**. Return the maximum number of instances that can be formed.
**Example 1:**

Input: text = "nlaebolko"
Output: 1
**Example 2:**
![](https://assets.leetcode.com/uploads/2019/09/05/1536_ex2_upd.JPG)
Input: text = "loonbalxballpoon"
Output: 2
**Example 3:**
Input: text = "leetcode"
Output: 0
**Constraints:**
- `1 <= text.length <= 10^4`
- `text` consists of lower case English letters only.
## 题目大意
给你一个字符串 text你需要使用 text 中的字母来拼凑尽可能多的单词 "balloon"气球。字符串 text 中的每个字母最多只能被使用一次。请你返回最多可以拼凑出多少个单词 "balloon"。
提示:
- 1 <= text.length <= 10^4
- text 全部由小写英文字母组成
## 解题思路
- 给出一个字符串,问这个字符串里面的数组能组成多少个 **balloon** 这个单词。
- 简单题,先统计 26 个字母每个字母的频次,然后取出 balloon 这 5 个字母出现频次最小的值就是结果。
