Consider the following system:

Threads: $4$ threads named T$0,$ T$1,$ T$2,$ and T$3$

Resource types: $2$ resource types: R$1(12$ instances$)$ and R$2(9$ instances$)$

Snapshot at time T$0$:

$\backslash$table$[[$Thread$,$Allocation,Max,Need,Available$],[,$AB$,$AB$,$AB$,$A B$],[$T$0,52,74,22,57],[$T$1,24,55,31,],[$T$2,41,64,23,],[$T$3,13,43,30,]]$

Is the system in a safe state?

If yes, what is the safe sequence?

If no$,$ can you modify the available resources to make it safe?

What would happen if T$1$ requests an additional instance of R$2?$

$5$ Suggest a resource allocation strategy that could prevent deadlocks in this system
