Final answer:
The question is about determining if a non-empty string can be segmented into words from a given dictionary using a dynamic programming approach. A boolean dynamic programming array is used to track which substrings can be formed. The resulting value at the end of the array indicates whether the entire string can be segmented.
Step-by-step explanation:
The question concerns the determination of whether a non-empty string s can be segmented into a sequence of one or more words that are contained within a given wordDict, which is a dictionary (or list) of non-empty words. This is a typical problem in the realm of computer science, particularly in the fields of algorithms and natural language processing. To solve this, a common approach is to use dynamic programming where you create a boolean array dp whose indices represent lengths of substrings and whose values indicate whether the substring (up to that length) can be segmented into words from the dictionary.
For example, if s = "leetcode" and wordDict = ["leet", "code"], the answer would be true since "leetcode" can be segmented into "leet code", which are both words in the dictionary. You start by initializing an array dp with the size of the string length plus one, setting all values to false except dp[0], which is true, signifying an empty substring.
Then, for each index i from 1 to the length of s, you would check if there is some index j less than i such that dp[j] is true and the substring s[j...i] is in the dictionary. If so, dp[i] becomes true. After filling out the array, the value at dp[s.length()] will determine if the whole string can be segmented successfully.
