For an input with the size of n, consider Alg1 to be a recursive algorithm structured as follows: For n = 1, Alg1 requires 3
For an input with the size of n, consider Alg1 to be a recursive algorithm structured as follows:
For n = 1, Alg1 requires 3 time units to return an answer.
For n > 1, Alg1 recurses 4 times on sub-problems each of size n 4 .
To combine the recursion results, Alg1 requires n calculation.
a) write the recurrence T(n) for the running time of Alg1
b) Using the recursion tree analysis method, solve T(n) and compute the asymptotic running time of Alg1.
