Solution: Word Break

Explore dynamic programming techniques to solve the Word Break problem by determining if a string can be segmented into valid dictionary words. Understand the drawbacks of naive recursive approaches and implement a lookup table method to optimize performance. This lesson helps you analyze time and space complexities while applying pointers and substring checks for an efficient solution.

Statement

Given a string, s, and a dictionary of strings, word_dict, check if s can be segmented into a space-separated sequence of one or more dictionary words. If yes, return TRUE; else, return FALSE.

Note: The same word in the dictionary may be used multiple times.

Constraints:

  • 11 \leq s.length 250\leq 250

  • 11 \leq word_dict.length 1000\leq 1000 ...
