# Ransom Note <img src="https://img.shields.io/badge/-easy-brightgreen">

Given an arbitrary ransom note string and another string containing letters from all the magazines, write a function that will return true if the ransom note can be constructed from the magazines ; otherwise, it will return false.

Each letter in the magazine string can only be used once in your ransom note.

**Example 1:**

Input: ransomNote = "a", magazine = "b"
Output: false

**Example 2:**

Input: ransomNote = "aa", magazine = "ab"
Output: false

**Example 3:**

Input: ransomNote = "aa", magazine = "aab"
Output: true

**Constraints:**
- You may assume that both strings contain only lowercase letters.

# Solution

class Solution:
    def canConstruct(self, ransomNote: str, magazine: str) -> bool:
        for letter in set(ransomNote):
            if ransomNote.count(letter) > magazine.count(letter):
                return False
        return True
