======= Problem Statement (based on my understanding) =========== Given:-

We will be given a dictionary of words. Each line of dictionary containing one word. A word can have punctuation and white spaces in it.

We will be provided with phone numbers in an input file or on STDIN

Aim:-

For each phone number read, this program should output all possible word replacements from a dictionary. This program should try to replace every digit of the provided phone number with a letter from a dictionary word; however, if no match can be made, a single digit can be left as is at that point. No two consecutive digits can remain unchanged and the program should skip over a number (producing no output) if a match cannot be made.

Jdk 1.8 or above version is required.

For testing we need junit-4.10.jar, hamcrest-core-1.1.jar, mockito-core-1.10.19.jar & objenesis-2.1.jar

If you want to recompile the project then you will need Gradle 2.11

Go to root directory of project i.e. in PhoneNumbersMatcher folder

Option 1:-

Run the program with default dictionary availabe in project.  Phone number will be entered on STDIN

Command --> java -cp ./build/classes/main/ com.naiyarv.Main -d src/resources/dictionary.txt

Option 2:-

Run the program with use provided dictionary availabe in project.  Phone number will be entered on STDIN

Command --> java -cp ./build/classes/main/ com.naiyarv.Main -d ${PATH_OF_DICTIONARY}

Option 3:-

Run the program with default dictionary availabe in project.  Use default phone number files provided in project

Command --> java -cp ./build/classes/main/ com.naiyarv.Main -d src/resources/dictionary.txt src/resources/phoneNumbers.txt src/resources/phoneNumbers_1.txt

Option 4:-

Run the program with use provided dictionary availabe in project.  Phone number files will be provided as argument.

Command --> java -cp ./build/classes/main/ com.naiyarv.Main -d ${PATH_OF_DICTIONARY}  ${PATH_OF_PHONE_FILE_1} ${PATH_OF_PHONE_FILE_2}
