CSIS-385: Quiz 3 Name____________________________________
1. Given the following code:
a and b are integers
n is the size of the input
basic_op is a basic operation
Mystery(a,b) {
if (a == b) {
for (x = 1 to n)
basic_op;
for (x = 1 to 2*n)
basic_op;
}
else {
for (x = 1 to n)
for (y = 1 to x)
basic_op;
}
}
a. What is the worst case running time,
i.e., f(n)=O(?)
Answer:
b. What is the best case running time,
i.e., f(n) = (?)
Answer:
c. Can we describe the average case
running time, i.e., f(n) = (?). If yes,
what is it? If no, explain why you can’t.

2. Given the following code:
a and b are integers
n is the size of the input
basic_op is a basic operation
Mystery(a,b) {
if (a == b) {
for (x = 1 to n+n)
basic_op;
for (x = 1 to n*n)
basic_op;
}
else {
for (x = 1 to 10)
for (y = 1 to x)
basic_op;
}
}
