How to resolve the algorithm I before E except after C step by step in the C# programming language

Problem Statement

The phrase     "I before E, except after C"     is a widely known mnemonic which is supposed to help when spelling English words.

Using the word list from   http://wiki.puzzlers.org/pub/wordlists/unixdict.txt, check if the two sub-clauses of the phrase are plausible individually:

If both sub-phrases are plausible then the original phrase can be said to be plausible. Something is plausible if the number of words having the feature is more than two times the number of words having the opposite feature (where feature is 'ie' or 'ei' preceded or not by 'c' as appropriate).

As a stretch goal use the entries from the table of Word Frequencies in Written and Spoken English: based on the British National Corpus, (selecting those rows with three space or tab separated words only), to see if the phrase is plausible when word frequencies are taken into account.

Step by Step solution about How to resolve the algorithm I before E except after C step by step in the C# programming language

The provided C# code pertains to a program that assesses the plausibility of a specific spelling rule using a word list. The rule under scrutiny is the preference for "ie" over "ei" when "c" is not present, and the exception being "cei." The program analyzes a word list (in this case, "unixdict.txt") to determine if the rule holds true for most words.

Here's a detailed breakdown of the code:

  1. Namespace and Class: The code resides within the IBeforeE namespace and the Program class.

  2. Plausibility Check Functions:

    • IsPlausibleWord: Checks if a word follows the plausible rule (ie when c is absent, or cei).
    • IsOppPlausibleWord: Checks if a word follows the opposite (implausible) rule (ei when c is absent).

  3. Plausibility Rule Assessment:

    • IsPlausibleRule: Reads a word list (specified by filename) and counts instances where words follow the plausible rule (IsPlausibleWord) or the opposite rule (IsOppPlausibleWord). It returns true if plausible instances exceed twice the implausible instances.

  4. Main Method:

    • The entry point of the program.
    • Calls IsPlausibleRule with the "unixdict.txt" word list.
    • Prints whether the rule is plausible (plausible count greater than twice the implausible count) or not.

The program essentially verifies if the provided rule aligns with the majority of words in the word list. If the plausible instances significantly outnumber the implausible ones, the rule is considered plausible; otherwise, it's not.
