Adding Big numbers
Write a program that will read 2 integers of 40 digits and print their sum (which may be up to 41 digits). The numbers will be on two separate lines in the file BigNumbers.txt. Name your program BigNumbersXxx.java where the “Xxx” is your user name.
Output: each number on a separate line, with the sum on a third line.
Note: be sure to consider carries from one column to the next.
