Problem statement

Given an integer inputNum, representing the number of elements in the set (N). The next line consists of N space-separated integers representing the elements of the given set.

Print K space-separated integers where the first number is the mean of the input numbers and the second number is the mode (where K=2).

Note

If mean calculated is in decimal, print its floor value (Floor is the greatest integer less than or equal to that number: floor[2.4] = 2).

Function

calculateMeanAndMode(inputNums: int[]) → int[]

Examples

Example 1

inputNums = [1, 2, 7, 3, 2]return = [3, 2]
The mean for the given set of numbers is 3 (1+2+7+3+2 = 15, 15/2=3). The mode is the most frequently occurring number which is 2. So, the output is 3, 2.
