0 votes 0 votes hello sir i have doubt in this question. T(n) >= 2T(n/2) + theta(n) option are: O(n log n) omega(n log n) theta (n log n) how we to select which sign i have to use omega ,big oh ,theta ??????

It should be ,T(n) <= 2T(n/2) + Θ(n), ultimately, T( n ) is a problem , we are dividing into small sub problems of size n/2 and then some linear time is required.. 0 votes 0 votes bhuv commented May 12, 2017 reply Follow Share Use recursion tree method to be precise about O, theta, omega. For general purpose use Master theorem rules. 0 votes 0 votes Please log in or register to add a comment.
0 votes 0 votes Here in ur question use Master Theorem use 2(a) as a=b and p=0 So a = 2,b=2,k=1,p=0 Using this we get nlogn, Now as T(n)>= function so use Omega So ans is Omega(nlogn) anonymous answered May 12, 2017 anonymous comment Share Follow See 1 comment See all 1 1 comment reply aaru14 commented May 12, 2017 reply Follow Share thanks 0 votes 0 votes Please log in or register to add a comment.
