The decimal number is equal to the sum of binary digits (dn) times their power of 2 (2^n):
decimal = d0×2^0 + d1×2^1 + d2×2^2 + ...
If binary is 1000, the corresponding decimal should be 1x2^3+0x2^2+0x2^1+0x2^0=8
So, what is the decimal number of 1010? 1*2^3+0*2^2+1*2^1+0*2^0=10.
Programming the Backdrop
When the game starts, a random integer between 1-16 appears in the middle of our screen as a decimal number that
needs to be converted by binary, and it is stored in the variable random.
Whether we receive a “right” result or a “wrong” result, we have to regenerate the random number and proceed to the
next round of the game.
