Compute the average waiting time for the following processes using preemptive priority scheduling. Assume all process have arrived at time $0$ and $1$

is the highest priority.

Process P$1$ has burst time $10$ and has priority $3$

Process P$2$ has burst time $1$ and has priority $1$

Process P$3$ has burst time $2$ and has priority $4$

Process P$4$ has burst time $1$ and has priority $5$

Process P$5$ has burst time $5$ and has priority $2$
