A sentence is a list of words that are separated by a single space with no leading or trailing spaces.

You are given an array of strings sentences, where each sentences[i]represents a single sentence.

Return the maximum number of words that appear in a single sentence.

Example 1:

Input: sentences = ["alice and bob love leetcode", "i think so too", "this is great thanks very much"]Output: 6Explanation: - 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: 3Explanation: 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.

Constraints:

1 <= sentences.length <= 100

1 <= sentences[i].length <= 100

sentences[i]consists only of lowercase English letters and ' 'only.

sentences[i]does not have leading or trailing spaces.

All the words in sentences[i]are separated by a single space.

判断数组中哪个字符串含有的单词最多，那么就是如何判断字符串含有多少个单词，我是根据如果这个字符串有多少个空字符+字母的数量，那么单词的数量就是这个数量加1；

之前想用string的 split函数，每次都报错，所以也就不用了。
