Ruby Program: Unique Four-Letter Sequences from a Dictionary

Objective

Write a Ruby program that extracts unique four-letter sequences from words in a dictionary file.

Requirements

• The program must generate two output files:
  • sequences.txt: Contains four-letter sequences that appear in exactly one word.
  • words.txt: Lists the corresponding word for each sequence, in the same order.
• Sequences are case-insensitive.
