题目说明
编写 function solution(logs, fields)。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。 logs:JSON[], fields:string[]. Match object keys case-insensitively against fields without trimming. Replace the entire matching value with '[REDACTED]'. Recurse into other objects and arrays; retain primitives and null. Preserve all keys, including '__proto__'. Maximum depth 20. Return a new array in input 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。
