Write a method that takes a matrix as parameter (2 dimen- sional array) and returns true if the matrix is identity matrix, false otherwise. V. QUESTION (15 POINTS) Write a recursive method int S (int n, int k) to calculate Stirling numbers of the first kind where S(n,n) = 1 S(n,0) = 0, if n0 S(n, 0) 1, if n = 0 S(n, k) = kS(n-1,k) + S(n-1, k-1) VI. QUESTION (20 POINTS) Write a method that reads N integers and returns the number of integers that are two standard deviation above or below the mean of those N numbers. Standard deviation of N numbers is calculated as: S= ..(*; - m) N-1 . Your method should use the following methods a method to read N integers a method to find the average of N numbers a method to find the standard deviation of N numbers which must also be implemented.
