Suppose there are 50 bottles of drink, 3 empty bottles can be replaced by a bottle of drink, and so on, how many bottles of drink in total?

That's all you can think.

A total of 50 bottles,

Finish three bottles + 1

Finish three bottles + 1

Then 50-3 + 1-3 + 1

And so you know ... The last remaining Coke number is less than 3 exit. Then still test instructions can write.

Package CCCC;
public class Buy {
public static void Main (string[] args) {
int number = 50; Total number of initial beverages
int i=0; Redemption Times
while (true) {
N-= 3; Drink 3 bottles.
n++; Redeem 1 Bottles
i++; Redemption Times +1
if (n<3)
{
System.out.println ("Drink Together" + (50+i) + "bottle");
Break
}
}
}
}
