Problem: Ransom Note

Easy
15 min
Understand how to solve the ransom note problem by efficiently tracking character occurrences. Learn to implement a solution that checks if the note can be formed from magazine letters using linear time and constant space complexity. This lesson helps you practice essential techniques for permutations and anagram-related coding challenges.

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.
