{ "data": { "question": { "questionId": "3541", "questionFrontendId": "3295", "categoryTitle": "Algorithms", "boundTopicId": 2924450, "title": "Report Spam Message", "titleSlug": "report-spam-message", "content": "
You are given an array of strings message and an array of strings bannedWords.
An array of words is considered spam if there are at least two words in it that exactly match any word in bannedWords.
Return true if the array message is spam, and false otherwise.
\n
Example 1:
\n\nInput: message = ["hello","world","leetcode"], bannedWords = ["world","hello"]
\n\nOutput: true
\n\nExplanation:
\n\nThe words "hello" and "world" from the message array both appear in the bannedWords array.
Example 2:
\n\nInput: message = ["hello","programming","fun"], bannedWords = ["world","programming","leetcode"]
\n\nOutput: false
\n\nExplanation:
\n\nOnly one word from the message array ("programming") appears in the bannedWords array.
\n
Constraints:
\n\n1 <= message.length, bannedWords.length <= 1051 <= message[i].length, bannedWords[i].length <= 15message[i] and bannedWords[i] consist only of lowercase English letters.给你一个字符串数组 message 和一个字符串数组 bannedWords。
如果数组中 至少 存在两个单词与 bannedWords 中的任一单词 完全相同,则该数组被视为 垃圾信息。
如果数组 message 是垃圾信息,则返回 true;否则返回 false。
\n\n
示例 1:
\n\n输入: message = [\"hello\",\"world\",\"leetcode\"], bannedWords = [\"world\",\"hello\"]
\n\n输出: true
\n\n解释:
\n\n数组 message 中的 \"hello\" 和 \"world\" 都出现在数组 bannedWords 中。
示例 2:
\n\n输入: message = [\"hello\",\"programming\",\"fun\"], bannedWords = [\"world\",\"programming\",\"leetcode\"]
\n\n输出: false
\n\n解释:
\n\n数组 message 中只有一个单词(\"programming\")出现在数组 bannedWords 中。
\n\n
提示:
\n\n1 <= message.length, bannedWords.length <= 1051 <= message[i].length, bannedWords[i].length <= 15message[i] 和 bannedWords[i] 都只由小写英文字母组成。\\u7248\\u672c\\uff1a
