# 2114. Maximum Number of Words Found in Sentences ## 題目概要 給定一個陣列 sentence,找出哪個句子中單字數最多,輸出該句子的單字數。 ``` Example 1: Input: sentences = ["alice and bob love leetcode", "i think so too", "this is great thanks very much"] Output: 6 Explanation: - The first sentence, "alice and bob love leetcode", has 5 words in total. - The second sentence, "i think so too", has 4 words in total. - The third sentence, "this is great thanks very much", has 6 words in total. Thus, the maximum number of words in a single sentence comes from the third sentence, which has 6 words. Example 2: Input: sentences = ["please wait", "continue to fight", "continue to win"] Output: 3 Explanation: It is possible that multiple sentences contain the same number of words. In this example, the second and third sentences (underlined) have the same number of words. ``` ## 解題技巧 - 用 split 分割每個句子的空格,分割後的 array 長度就代表該句子的單字長度,判斷所有句子哪個單字數最多。 ## 程式碼 ```js var mostWordsFound = function(sentences) { let max = 0; for (let ele of sentences) { const arr = ele.split(" "); max = Math.max(arr.length, max); } return max; }; ``` ![](https://i.imgur.com/RmCYsO6.png)
