Use a recursion tree to determine a good asymptotic upper bound on therecurrence T(n) = 3T(n/2) + n. Use the substitution method to prove your answer.
Use a recursion tree to determine a good asymptotic upper bound on following recurrences. Please see Appendix of your text book for using harmonic and geometric series.
a) T (n) = T(n/5) + O(n)2
b) T (n) = 10T(n/2) + O(n)2
c) T (n) = 10T(n/2) + Θ (1)
d) T (n) = 2T (n/2) + n/ lg n
e) T (n) = 2T (n - 1) + Θ (1)
for the following problem we need to use a recursion tree. so we can determine an asymptotic upper bound on therecurrence T(n) = 3T(n/2) + n. the substitution method must be used to solve.
