Word Break

Description

This implementation introduces the "Word Break" functionality, a feature that determines whether a given string can be segmented into a sequence of one or more words from a provided list. The solution uses a combination of Trie data structure and dynamic programming, offering efficient word lookup and optimal substructure for segmentation checks.

The algorithm involves building a Trie from the list of words, which allows for fast and efficient prefix searches. With the Trie, we can efficiently scan the string for available words starting from each position. Dynamic programming is then employed to remember and reuse the results of sub-problems, reducing redundant computations.

This method is particularly useful in natural language processing and word parsing scenarios, where such segmentation checks are frequent.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist:

• I ran bellow commands using the latest version of rust nightly.
• I ran cargo clippy --all -- -D warnings just before my last commit and fixed any issue that was found.
• I ran cargo fmt just before my last commit.
• I ran cargo test just before my last commit and all tests passed.
• I added my algorithm to the corresponding mod.rs file within its own folder, and in any parent folder(s).
• I added my algorithm to DIRECTORY.md with the correct link.
• I checked COUNTRIBUTING.md and my code follows its guidelines.

Could you implement it using this Trie? https://github.com/TheAlgorithms/Rust/blob/da08798f02653dc5b5a02bce176a31d4c8ed9d42/src/data_structures/trie.rs
