Solve the following recurrence relation. You could use the Master Theorem or any other method seen in class. T(n) = T(n/10) + n²
There is a distinction between the bracketing approach and the open method. explain

Q1. Let’s play a dice game with a pair of dice following these rules:1. At the beginning, you throw a pair of dice. If the two numbers add up to 5, 6, 7, 8, or 9, thegame immediately stops.2. If your first throw does not meet those 5 totals, you would continue until you get either 11 or12.Get 1000 simulations of this paired dice game. What is the average number of dice throw per game?You can use the sample() function to simulate the dice.
