Leetcode Problem 1189. Maximum Number of Balloons

1189. Maximum Number of Balloons

Leetcode Solutions

Counting Characters Approach

  1. Initialize a dictionary to store the frequency of the characters 'b', 'a', 'l', 'o', and 'n' in text.
  2. Iterate over each character in text and update the frequency in the dictionary.
  3. Since 'l' and 'o' are needed twice in 'balloon', divide their frequencies by 2.
  4. Find the minimum frequency among these characters, which will be the bottleneck.
  5. Return the minimum frequency as the maximum number of 'balloon' instances that can be formed.
