LeetCode Meditations: Word Break

  • Given a string s and a dictionary of strings wordDict, return true if s can be segmented into a space-separated sequence of one or more dictionary words.
  • The problem involves constructing a dynamic programming (dp) array to track whether it is possible to break the string s into words in wordDict at each index.
  • The approach involves iterating backwards and checking if any word in wordDict can be reached from each index onwards.
  • The time complexity is O(n∗m∗t) and the space complexity is O(n), where n is the length of s, m is the number of words in wordDict, and t is the maximum length word in wordDict.
