(a) Create a function called makeLayered that takes a single parameter n and returns a square 2D array that has 1 at its centre and layers of numbers around this increasing up to and including the value n. For example: makeLayered(3) will return the 2D array 3 3 3 3 2 2 3 1 2 3 2 2 3 3 3 3 (b) Give three test cases for the makeLayered function that will test a range of outcomes. For each test case explain what types of inputs that case is testing and give the expected output. m 33 33
