Q$\mathrm{.}11.(10$ points$)$ There are six programs P$1,$ P$2,$ P$3,$ P$4,$ P$5$ and P$6$ of sizes $15$KB$,20$KB$,20$KB$,25$KB$,25$B and $15$KB respectively. They are submitted to the system in the order P$1,$ P$2,$ P$3,$ P$4,$ P$5,$ P$6$ and they finish in the same order. Size of the main memory is $75$KB$.$ Show the contents of the memory for each of the following partitioning methods. a$.$ Fixed size partitioning where each partition is $25$KB HA b$.$ Variable size partitioning c$.$ Relocatable partitioning
