Consider a physical memory of size $2^64$ KB which is managed by buddies' scheme. Suppose a set of five processes namely P$1,$ P$2,$ P$3$ P$5$ Demand memory requirement of size $2028$ KB$,112$KB$,288$ KB$,598$ KB and $25$KB respectively. What would be the size of the memo allocated to these programs? Draw the allocation tree. Is it fair allocation? Justify
