Write a program where the player has to guess the number.

The program will pick a random number and store it, but not print it out. The player takes turns picking numbers until they guess correctly.

Then the program will loop, in each loop it will:

• get the player's guess
• if the answer is higher than the guess, print 'higher'
• if the answer is lower than the guess, print 'lower'
• if the answer is equal to the guess, print a winning message and exit
• continue to loop until the guess is equal to the answer
