T(n) = sqrt(n) * T(sqrt(n)) + n
T(n) = sqrt(n) * T(sqrt(n)) + n Given solution is O(log log n). But my solution is O(n log log n). 'wolframalpha'' shows the answer same as mine. You can find the solution here. Can anyone confirm the solution and provide an explantion?

O($2^{m+n}$) O($2^{n}$) O($2^{mn}$) O($2^{max(m,n)}$) none of these
