// 1189. Maximum Number of Balloons

// Given a string text, you want to use the characters of text to form as many instances of the word "balloon" as possible.

// Input: text = "nlaebolko"
// Output: 1
// Example 2:



// Input: text = "loonbalxballpoon"
// Output: 2
// Example 3:

// Input: text = "leetcode"
// Output: 0
