We are playing the Guess Game. The game is as follows:
I pick a number from 1 to n. You have to guess which number I picked.
Every time you guess wrong, I’ll tell you whether the number is higher or lower.
You call a pre-defined API
guess(int num) which returns 3 possible results (
-1 : My number is lower
n = 10, I pick 6.
/* The guess API is defined in the parent class GuessGame.
