Consider the following game: You have a random number generator that produces in every round an integer number from 
to 
with equal probability. You play 3 rounds and have to decide at which position of a 3 digit number you want to place the random digit. Your goal is to form the largest possible (decimal) number. Formulate this game as a Markov decision process and find an optimal policy. Also analyze the case where the numbers are drawn without replacement, i.e. if the digit
appears in the first round, it cannot appear anymore in the remaining two rounds.
