Design and implement a iterative program to determine and print the Nth line of Pascals's Triangle. THIS MUST BE DONE IN JAVA

A) The solution MUST BE ITERATIVE

B) You must describe in detail how the solution is iterative. Refer to the line number(s) in the program.

C) You cannot print out the entire triangle, but must ask for user input instead. The user input will be the desired line in the Pascal triangle with the 15th line being the maximum.
