Solution: Word Break II

Understand how to solve the Word Break II problem by applying dynamic programming techniques. This lesson guides you through building a solution that efficiently breaks a string into valid dictionary words, using bottom-up approaches to optimize time and space complexity. Learn to create and utilize a table to store subproblem results and produce all possible valid sentence combinations.

Statement

You are given a string, s, and an array of strings, wordDict, representing a dictionary. Your task is to add spaces to s to break it up into a sequence of valid words from wordDict. We are required to return an array of all possible sequences of words (sentences). The order in which the sentences are listed is not significant.

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

Constraints:

  • 11 \leq s.length 20\leq 20 ...
