Consider the following two transactions:

T$\_(34)$:read$($A$)$;

read$($B$)$;

if A$=0$ then B:$=$B$+1$;

write $($B$).$

T$\_(35)$:read$($B$)$;

read$($A$)$;

if B$=0$ then A:$=$A$+1$;

write $($A$).$

Add lock and unlock instructions to transactions T$\_(34)$ and T$\_(35)$ so that they observe the two$-$

phase locking protocol. $(40$ points$)$

Here are some instructions you can use:

Lock$-$S$($A$)$

Lock$-$S$($B$)$

Lock$-$X$($A$)$

Lock$-$X$($B$)$

Unlock$($A$)$

Unlock$($B$)$

Can the execution of these transactions result in a deadlock? $($Just Yes or No$)(5$ points$)$
