Problem: Ransom Note

Medium
30 min
Explore how to verify if one string can be constructed from another by tracking data effectively. This lesson helps you understand solving permutations and anagrams using an optimal approach that balances time and space complexity. Practice implementing a solution that runs in linear time and constant space.

Statement

Given two strings, ransom_note and magazine, check if ransom_note can be constructed using the letters from magazine. Return TRUE if it can be constructed, FALSE otherwise.

Note: A ransom note is a written message that can be constructed by using the letters available in the given magazine. The magazine can have multiple instances of the same letter. Each instance of the letter in the magazine can only be used once to construct the ransom note.

Constraints:

  • 11 \leq ransom_note.length , magazine.length 103\leq 10^3

  • The ransom_note and magazine consist of lowercase English letters.
