LeetCode 1023. 驼峰式匹配(C++)

如果我们可以将小写字母插入模式串 pattern 得到待查询项 query,那么待查询项与给定模式串匹配。(我们可以在任何位置插入每个字符,也可以插入 0 个字符。)

给定待查询列表 queries,和模式串 pattern,返回由布尔值组成的答案列表 answer。只有在待查项 queries[i] 与模式串 pattern匹配时, answer[i] 才为 true,否则为 false

示例 1:

输入:queries = ["FooBar","FooBarTest","FootBall","FrameBuffer","ForceFeedBack"], pattern = "FB"
输出:[true,false,true,true,false]
示例:
"FooBar" 可以这样生成:"F" + "oo" + "B" + "ar"。
"FootBall" 可以这样生成:"F" + "oot" + "B" + "all".
"FrameBuffer" 可以这样生成:"F" + "rame" + "B" + "uffer".

示例 2:

输入:queries = ["FooBar","FooBarTest","FootBall","FrameBuffer","ForceFeedBack"], pattern = "FoBa"
输出:[true,false,true,false,false]
解释:
"FooBar" 可以这样生成:"Fo" + "o" + "Ba" + "r".
"FootBall" 可以这样生成:"Fo" + "ot" + "Ba" + "ll".

示例 3:

输出:queries = ["FooBar","FooBarTest","FootBall","FrameBuffer","ForceFeedBack"], pattern = "FoBaT"
输入:[false,true,false,false,false]
解释: 
"FooBarTest" 可以这样生成:"Fo" + "o" + "Ba" + "r" + "T" + "est".

提示:

1 <= queries.length <= 100

1 <= queries[i].length <= 100

1 <= pattern.length <= 100

所有字符串都仅由大写和小写英文字母组成。

C++

class Solution {
public:
    bool func(string a, string b)
    {
        int n=a.length();
        int k=0;
        for(int i=0;i<n;i++)
        {
            if(k<b.length() && a[i]==b[k])
            {
                k++;
            }
            else
            {
                if(a[i]>='A' && a[i]<='Z')
                {
                    return false;
                }
            }
        }
        if(k==b.length())
        {
            return true;
        }
        return false;        
    }
    
    vector<bool> camelMatch(vector<string>& queries, string pattern) 
    {
        vector<bool> res;
        int m=queries.size();
        for(int i=0;i<m;i++)
        {
            bool flag=func(queries[i],pattern);
            res.push_back(flag);
        }
        return res;
    }
};
