A Write A Program To Determine If A Positive Integer

a. Write a program to determine if a positive integer, N, is prime.
b. In terms of N, what is the worst-case running time of your program? (You should be able to do this in O(√N).)
c. Let B equal the number of bits in the binary representation of N. What is the value of B?
d. In terms of B, what is the worst-case running time of your program?
e. Compare the running times to determine if a 20-bit number and a 40-bit number are prime.
f. Is it more reasonable to give the running time in terms of N or B? Why?
