public static int threeHeads() { // Counts coin tosses till we get heads 3x in a row.
Random rand = new Random();
int flip = 1;
int heads = 0;
int count = 0;
// Point A
while (heads < 3) {
// Point B
flip = rand.nextInt(2); // flip coin
if (flip == 0) { // heads
heads++;
// Point C
} else { // tails
// Point D
heads = 0;
}
count++;
}
// Point E
return count;
}
$\begin{array}{|l|l|l|l|}\hline & f l i p==0 & \text { heads }==0 & \text { flip }>\text { heads } \\\hline \text { Point A } & & & \\\hline \text { Point B } & & & \\\hline \text { Point C } & & & \\\hline \text { Point D } & & & \\\hline \text { Point E } & & & \\\hline\end{array}$
