Bold Words In String is an example of string problems. In this post we will see how we can solve it in Javascript.

Problem Description

Given a set of keywords words and a string S, make all appearances of all keywords in S bold. Any letters between and 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 "aabcd".

Note that returning "aabcd" would use more tags, so it is incorrect.

Note:

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