Daily Coding Problem: Problem #178 [Hard]

Good morning!

Here's a solution to yesterday's problem.

This is your coding interview problem for today.

This problem was asked by Two Sigma.

Alice wants to join her school's Probability Student Club. Membership dues are computed via one of two simple probabilistic games.

The first game: roll a die repeatedly. Stop rolling once you get a five followed by a six. Your number of rolls is the amount you pay, in dollars.

The second game: same, except that the stopping condition is a five followed by a five.

Which of the two games should Alice elect to play? Does it even matter? Write a program to simulate the two games and calculate their expected value.

We will be sending the solution tomorrow, along with tomorrow's question. As always, feel free to shoot us an email if there's anything we can help with.

Have a great day!
