771. Jewels and Stones 由于是按难易度排序的，因此本题是第一题。 题目链接 771. Jewels and Stones 题目分析 从第二个参数S中找第一个参数J 中出现的字符，返回找到的字符个数。 也就是说，第一个参数J是一个需要找的字符的列表...
题目链接：Jewels and Stones 思路：从题目得知，我们是求字符串J在字符串S中出现的次数。也就是说，one-pass就可以brute force获得答案。当然可以利用set()数据结构进行优化。 算法复杂度： 时间：O(M*N) or O(M + N) where M is the length of...
