Question: 11. Petersons mutual exclusion algortihm for two processes is shown in Figure 12.34. (a) Show that it satisfies mutual exclusion, progress, and bounded waiting. (b)

11. Peterson’s mutual exclusion algortihm for two processes is shown in Figure 12.34.

(a) Show that it satisfies mutual exclusion, progress, and bounded waiting.

(b) Use this algorithm as a building block to construct a hierarchical mutual exclusion algorithm for an arbitrary number of processes. (Hint: use a logarithmic number of steps in the hierarchy.)
