Spelling Checker

This program checks for any spelling errors in a given file using a given dictionary.
Dictionary is created in the memory as a map. Each entry in the map has an arraylist of words starting with the same letter that used as the key for the entry.
Words in the arraylist are ordered alphabetically at first. During the spell checking process, words are reordered according to their total access (hit) counts in realtime.

To compile:

gcc spell_checker.c -o spell_checker

Usage:

spell_checker <dictionary_file> <file_to_check>

Sample input:

./spell_checker sampleDictionary.txt sampleFile.txt
