# [383. Ransom Note](https://leetcode.com/problems/ransom-note/description/)
# 思路
用一个大小为26的数组count记录magazine中26个字母的出现次数，只要每个字母出现次数不小于ransomNote对应字母次数就行了。
# C++
```C++
class Solution {
public:
    bool canConstruct(string ransomNote, string magazine) {
        vector<int>count(26);
        for(char c: magazine) count[c - 'a']++;
        for(char c: ransomNote)
            if(0 > --count[c - 'a']) return false;
        return true;
    }
};
```
