answer in big-O notation: T(n) = 2T( 
n 
2 
) + log(n) for n > 1, 0 otherwise 
• T(n) = O(n) 
• T(n) = O(nlogn) 
• T(n) = O(n 
2 
)

1.1 Rationale 
This recurrence relation can be tricky to solve using iterative substitution 
or tree-based methods. It’s best to use the Master theorem here. Recall the 
form: 
T(n) = aT(n/b) + f(n)
