/**

* Write a program to play the number guessing game. The program shall

* generate a random number between 0 and 99. The player inputs his/her guess,

* and the program shall response with "Try higher", "Try lower" or

* "You got it in n trials" accordingly. For example:

*

* > java NumberGuess

* Key in your guess:

* 50

* Try higher

* 70

* Try lower

* 65

* Try lower

* "You got it in 4 trials!"

*

* Hints: Use Math.random() to produce a random number in double between 0.0

* and (less than) 1.0. To produce an int between 0 and 99, use:

*

* int secretNumber = (int)(Math.random()*100);
