Chapter 5, Problem 31PS

If originally $\text{x}=\text{2, y}=\text{1, and z}=\text{1,}$ what is the value of x, y, and z after executing the following code?

$\begin{array}{|l|}\hline \text{switch }\left(\text{x}\right)\hfill \\ \text{{}\hfill \\ \text{case 0 : x}=\text{2;}\hfill \\ \text{y}=\text{3;}\hfill \\ \text{case 1 : x}=\text{4;}\hfill \\ \text{break;}\hfill \\ \text{default:}\hfill \\ \text{y}=\text{3;}\hfill \\ \begin{array}{l}\text{x = 1;}\\ \text{}}\end{array}\hfill \\ \hline\end{array}$
