The formula for a combination of n objects in groups of r is n!/(n-r)!. A use for this formula would be to calculate how many ways five people can win a race where there is a 1st, 2nd and 3rd place. This is the same as saying how many ways can you order five objects in only three positions. Using the above formula we would set n=5 and r=3 and calculate 5!/(5-3)! which simplifies to 5*4*3 or 60 possible ways. Write a function factorial() which accepts an integer as input and returns the factorial of the input. Write a function combinations() which accepts 2 integer parameters and calls the factorial() function to calculate the number of combinations Write a program which uses the above functions in a nested loop and calculates all combinations for 1 to 6 objects. Sample output The number of combinations of 1 objects in groups of 1 is 1 The number of combinations of 2 objects in groups of 1 is 2 The number of combinations of 2 objects in groups of 2 is 2 The number of combinations of 3 objects in groups of 1 is 3 The number of combinations of 3 objects in groups of 2 is 6 The number of combinations of 3 objects in groups of 3 is 6 The number of combinations of 4 objects in groups of 1 is 4 The number of combinations of 4 objects in groups of 2 is 12 The number of combinations of 4 objects in groups of 3 is 24 The number of combinations of 4 objects in groups of 4 is 24 The number of combinations of 5 objects in groups of 1 is 5 The number of combinations of 5 objects in groups of 2 is 20 The number of combinations of 5 objects in groups of 3 is 60 The number of combinations of 5 objects in groups of 4 is 120 The number of combinations of 5 objects in groups of 5 is 120 The number of combinations of 6 objects in groups of 1 is 6
