Write a pseudocode procedure called isprime that takes a integer n and returns true if n is a prime number and false otherwise. use the following algorithm: if n is less than 2 then return false. otherwise use a while loop to test n for divisibility by all integers from 2 up to the floor of the square root of n. within the loop, if n is divisible by i, return false. after the loop is done, return true. write pseudocode, as in the textbook. do not use c++ or any actual programming language.
