GATE 1999  Time Complexity
Match the following 1.T(n) = T(n1) +n a. O(n) 2. T(n) = T(n/2) +n b.O(nlogn) 3.T(n) = T(n/2) +nlogn c.O(n^2) 4.T(n) = T(n1) + logn d.O(log^2 n) The first one I did by substitution ... solve no 4,i tried it by substitution i got log(n!) by using stirling approx which is nlogn also,as it is a gate qs,pls someone give me detailed solution.
