There are several ways to compute the determinant of an n x n matrix. In this task, we ask you to implement a simple method that considers elements from the top row and their respective minors. The determinant of a matrix A, det(A) is given by an alternate sum of the products between each element of the top row with its minor. det (A) = 4 1 2 3 4 5231 250 1 3242 a e i m n o p b c d f g h j k l As you notice, this is a recursive definition that can be easily implemented with recursion. You can use the following fact to define the base case. For any 1 x 1 matrix A = [a], det(A) = |a| = a Requirement: You must only use pointers to maintain the matrices' data. Output: f g h| e gh ef h k 1+ci jl = aj k 1-bi n o p | m o pl m n pl m n ol -105.00000 Input & Output Your program should read input from the standard input. The first line of the input is n and each of the next n lines contain n integers aij (-1000 ≤ ajj ≤ 1000). The output of your program should be the value of the determinant accurate to 5 decimal places. Input: e f -dijk There are several ways to compute the determinant of an n x n matrix.
