题目说明
编写 function solution(rules, requests)。输入输出均为 JSON 值，不要修改输入数组或对象。不支持外部库、网络访问及异步函数。 rules:{effect,subject,action,resource}[]; requests:{subject,action,resource}[]. A rule matches when each field is '*' or an exact case-sensitive match. Any matching 'deny' overrides every allow. Otherwise allow if a matching 'allow' exists, deny by default. Ignore other effects. Rule order does not matter. Return booleans in request order. 输入范围：每个输入数组最多50,000项，每个字符串最多1,000个字符。数字必须有限，整数及整数累计结果在JavaScript安全整数范围内。其他类型和有效性遵循上述规则。
