Recurrence equations: (a) (10 points) Consider an algorithm with the recurrence formula \\[ T(n)=3 T\\left(\\frac{n}{3}\ ight)+\\sqrt{n}, \\quad T(0)=0 . \\] What is the running time of this algorithm? Your expression should be in \\( \\Theta \\). (b) (10 points) How much can we increase the overhead of the algorithm at each iteration without asymptotically changing the overall run-time? Hint: Replace, the overhead with \\( c n^{p} \\) and determine bounds on \\( c \\) and \\( p \\)
