CSE 222/505 – Homework 2
Give running times of each of the algorithms in proper notations. Explain your answers.
1. What does the function do?
2. Give the best-case and worst-case running times of the algorithm in Ɵ notation.
Explain your answer.
Prove that the running time of an algorithm is Ɵ(g(n)) if and only if its worst-case running
time is O(g(n)) and its best-case running time is Ω(g(n)).
1. Express insertion sort as a recursive procedure.
2. Write a recurrence for the worst-case running time of the procedure. Explain your
3. Solve the recurrence. Give detailed answer.
Indicate giving detailed explanation whether f(n) = O(g(n)), f(n) = Ω(g(n)) or f(n) = Ɵ(g(n)) for
1. 𝑓(𝑛) = 𝑛
, 𝑔(𝑛) = (log 𝑛)
2. 𝑓(𝑛) = 𝑛!, 𝑔(𝑛) = 2
3. 𝑓(𝑛) = (log 𝑛)
, 𝑔(𝑛) = 2
