Word Break is a medium coding interview question covering dynamic programming, strings — the kind asked at FAANG (Facebook/Meta, Apple, Amazon, Netflix, Google) and AI-first companies like Anthropic, OpenAI, and Nvidia.
Given a string s and a dictionary wordDict, return true if s can be segmented into space-separated dictionary words.
Example: s="leetcode", wordDict=["leet","code"] -> true Example: s="catsandog", wordDict=["cats","dog","sand","and","cat"] -> false
Words from the dictionary can be reused.
