Fill in the missing code BELOW where it says "student provides missing code"
The program output will look this after complete. Please upload screenshot with how it looks compiled along with the source code.
Problem
Allow the user to specify the number-of-sides of a die, S, the number-of-dice, D, and the number-of-trials, T. Because there is no requirement to validate user input, you may safely assume
(1 £ S £ 11), (1 £ D £ 11), and (T ³ 1)
By definition, a trial consists of repeatedly throwing the D Ssided dice until all the dice thrown show exactly the same face. For example, for S = 6 and D = 2, 1 trial might require the 8 throws (1,6) (2,3) (1,4) (5,6) (2,5) (4,6) (3,4) and finally (2,2).
After all trials have been run, display 1 line which shows the minimum number-of-throws used for a trial, the maximum number-of-throws used for a trial, and the average of the number-of-throws used for all trials using the format shown below. Note#1 The average is the real number which is computed as the quotient of the sum of number-of-throws for all trials (numerator) and the number-of-trials (denominator).

123456789012345678901234567890123456789012345678901234567
Minimum XXXXXXXXXX, maximum XXXXXXXXXX, average XXXXXXXX.X
Note #2 Your Monte Carlo simulation is attempting to show the average number-of-throws required for D S-sided dice is SD/S = SD-1, the number predicted by the theory of the geometric distribution which is implicit in the dice-throwing experiment.
