In this video you will find good examples on Time complexity using Recursion Tree method explained in a detailed and easy way.

eg1. What is the complexity of T(n) = 2T(n/2) + C
eg2. T(n)=T(n/3) + T(2n/3) + n

Please share your valuable comments.

didi...ek question hai...iska worst case m big o nikalna hai...
int &V, int k, int start, int end) {
if (start > end) return 0;
int mid = (start + end) / 2;
if (V[mid] < k) return searchNumOccurrence(V, k, mid + 1, end);
if (V[mid] > k) return searchNumOccurrence(V, k, start, mid - 1);
return searchNumOccurrence(V, k, start, mid - 1) + 1 + searchNumOccurrence(V, k, mid + 1, end);

ye function to binary ka hai...lekin last m return 2 aur recursive chal rha h...

Ma'am your teaching is great 💯
I have one doubt, please help me in this question :
T(n)=8T(n/2) + n^2
Solve by recurrence tree method.
