Problem 2106. Compute circular convolution

In signal processing, we usually encounter the circular convolution case. Compute it here using the two input sequences (denoted as row vectors) x(n) and h(n) with the same length N. Output the circular convolution.

Example

 x(n) = [1 2 0 1]
 h(n) = [2 2 1 1]

The result should be

 y(n) = [6 7 6 5]
