[LeetCode] Bold Words in String 字符串中的加粗单词

Given a set of keywords words and a string S, make all appearances of all keywords in S bold. Any letters between <b> and </b> tags become bold.

The returned string should use the least number of tags possible, and of course the tags should form a valid combination.

For example, given that words = ["ab", "bc"] and S = "aabcd", we should return "a<b>abc</b>d". Note that returning "a<b>a<b>b</b>c</b>d" would use more tags, so it is incorrect.

Note:

  1. words has length in range [0, 50].
  2. words[i] has length in range [1, 10].
  3. S has length in range [0, 500].
  4. All characters in words[i] and S are lowercase letters.

以空格为分隔符,判断一个string可以被分成几部分. 注意几种情况:(1)全都是空格 (2)空字符串(3)结尾有空格 思路: 只要统计出单词的数量即可.那么我们的做法是遍历字符串,遇到空格直接跳过,如果不是空格,则计数器加1,然后用个while循环找到下一个空格的位置,这样就遍历完了一个单词,再重复上面的操作直至结束,就能得到正确结果: class Solution { public: int countSegments(string s) { int res = 0, n = s.size(
