Repeat Exercise 3.17 for the case when the overlap-and-add method is used.

Exercise 3.17

We want to compute the linear convolution of a long sequence \(x(n)\), of length \(L\), with a short sequence \(h(n)\), of length \(K\). If we use the overlap-and-save method to compute the convolution, determine the block length that minimizes the number of arithmetic operations involved in the convolution.
