How to check if each letter in a string maps to the first letter of a word in another string with C#

Answer 1

using System;

class Program
{
    static bool MatchesPattern(string pattern, string sentence) {
        string[] words = sentence.Split(
            new[] { ' ' }, 
            StringSplitOptions.RemoveEmptyEntries
        );

        // Length mismatch → automatic failure
        if (pattern.Length != words.Length)
            return false;

        // Compare each pattern character to the first letter of each word
        for (int i = 0; i < pattern.Length; i++) {
            char p = char.ToLower(pattern[i]);
            char w = char.ToLower(words[i][0]);

            if (p != w)
                return false;
        }

        return true;
    }

    static void Main()
    {
        string pattern = "jpcrg";
        string sentence = "java python c rust go";

        if (MatchesPattern(pattern, sentence))
            Console.WriteLine("Pattern matches!");
        else
            Console.WriteLine("Pattern does NOT match.");
    }
}
