cannot be solved using master’s theorem

[Solved] 7 T (n/2) + 1/n

Q.	7 T (n/2) + 1/n
A.	t(n) = o(n)
B.	t(n) = o(log n)
C.	t(n) = o(n2log n)
D.	cannot be solved using master’s theorem
Answer» D. cannot be solved using master’s theorem
Explanation: the given recurrence cannot be solved by using the master’s theorem. it is because in this recurrence relation a < 1 so master’s theorem cannot be applied.
