1. In a programming language DWPLANG, a multidimensional homogeneous array (e.g., 3D case: A[1..N,1..M,1..R], NxMxR) is represented as vector of pointers that point to other vectors of pointers to as many levels as the array dimensions. For example, a 2x3x4 matrix of numbers is represented by a vector of two pointers, each of which points to another vector of three pointers. Finally, each of those three pointers points to vector of four numbers. Write down the access function to access A[I,J,K], when such representation is used. A[1,J,K]
