Phrase Ladder Recreation
Recreation Description
Phrase Ladder is a phrase recreation during which two gamers attempt to remodel one phrase into one other by altering one letter at a time, with every intermediate step being a sound phrase. For instance, to remodel the phrase “CAT” into the phrase “DOG”, one attainable phrase ladder is:
CAT -> COT -> DOT -> DOG
Gamers take turns making a transfer. On every transfer, a participant can change one letter of the phrase to create a brand new legitimate phrase. The primary participant who efficiently transforms the beginning phrase into the ending phrase wins the sport.
Necessities
Write a PHP perform known as wordLadder that enables two gamers to play a recreation of Phrase Ladder. The perform ought to take two parameters: the beginning phrase and the ending phrase.
The perform ought to immediate the primary participant for his or her transfer (the brand new phrase to create), validate the transfer (the brand new phrase must be one letter completely different from the earlier phrase and must be a sound English phrase), show the present state of the sport, and swap to the second participant if the transfer is legitimate.
The perform ought to proceed the sport till one participant efficiently transforms the beginning phrase into the ending phrase or no legitimate transfer might be made. The perform ought to return the successful participant (‘Participant 1’ or ‘Participant 2’) or ‘Tie’ if the sport is a tie.
The perform ought to use a dictionary file to validate phrases. You may obtain a dictionary file from http://www.gutenberg.org/ebooks/29765.
