/*
1.2.15 Built-in Types of Data
Write a program that takes three positive integers as commandline arguments and prints true 
if any one of them is greater than or equal to the sum of the other two and false otherwise. 
(Note: This computation tests whether the three numbers could be the lengths of the sides of 
some triangle.)
