The goal is to explore Shuttle.rs by implementing a sort of comparator that would take "mistaken data" as input. For example "house" and "h2se" should return true as the 2 here represents 2 missing characters, matching the total len of 5 plus the existing characters match.

An example that would not match is "house" and "h2an". They both have len of 5 but characters at the same index do not match.

The project is available at https://similarr.shuttleapp.rs. You can then call the /compare endpoint providing the strings a and b for comparison like this:

curl https://similarr.shuttleapp.rs/compare\?a\=house\&b\=ho2e

{
  "a": "house",
  "b": "ho2e",
  "expanded_a": "house",
  "expanded_b": "ho**e",
  "result": true
}

The input strings can have up to 50 characters (on submit), and the numbers in it can represent up to 30. For example, "a55b" is not allowed.
