Terminology
===========

All of the following terms are valid in the context of a specific Wordle.

* A set of **known letters** is a set of letters which are known to be present in the Wordle's word based on clues obtained from the previous attempts.
* A set of **valid words** at any given point refers to a set of words from vocabulary that are possible solutions to the Wordle at that point based on the clues obtained till then.
* A letter is said to **cover** a word if the letter belongs to that word.
* **Coverage** *(absolute)* of a word refers to the percentage of valid words (at that point) covered by the letters in that word.
* **Coverage** *(relative)* of a word refers to the percentage of valid words (at that point) covered by the set of

Solver
======

Solver roughly uses the following strategy,

* Guess a word with highest (relative) coverage.
* After each guess, eliminate words based on the clues, e.g.,
    * Remove all words that contain an :code:`incorrect-letter`
    * Remove all words that do not contain the identified :code:`(correct-letter, correct-position)` combinations
    * Remove all words that contain the identified :code:`(correct-letter, incorrect-position)` combinations
    * Remove all words that do not contain a :code:`correct-letter`
    * Re-calculate (relative) coverage and guess again
* If at any point, number of valid words drops below number of attempts left, guess the valid words one-by-one.
* Additionally, there are heuristics to choose a word if multiple words with best coverage-score exist.

Helper
======

Helper mode can be used to get assistance while solving Wordle from another provider.

* Suggestions for words will be provided at each step.
* You may choose a word and obtain result.
* Enter the obtained result as a ternary string, i.e., a string made of 0, 1, and 2.
    - 0 : (grey)   : an incorrect letter.
    - 1 : (yellow) : a correct letter in wrong position.
    - 2 : (green)  : a correct letter in correct position.
* e.g., if the third letter turned green and fifth letter turned yellow in the third party Wordle, then you should input 00201 as the result obtained.
