Sample Output :

Welcome to the High/Low game.I will pick a random number from 0 to 100.
You must try to guess the number.
What is your guess? (0 to 100)
56
56 is high.Try a lower number.
Now you have 6chances left.
What is your guess? (0 to 100)
28
28 is low.Try a higher number.
Now you have 5chances left.
What is your guess? (0 to 100)
36
36 is low.Try a higher number.
Now you have 4chances left.
What is your guess? (0 to 100)
46
46 is high.Try a lower number.
Now you have 3chances left.
What is your guess? (0 to 100)
40
40 is correct. Congratulations!
Your score is 42
Thank you for playing High/Low!
Want to play it again? (y/n)...
