// Short cut! Have you already done the matrix exercise?
// If it seems helpful, copy your code from the matrix exercise
// to this directory so you have access to it. You can leave it as matrix.go
// and start a new file saddle_points.go with additional code that completes
// this exercise. Submit only saddle_points.go for this exercise.
