Java BigInteger - Hacker Rank Solution
Java BigInteger – Hacker Rank Solution

Problem :

In this problem, you have to add and multiply huge numbers! These numbers are so big that you can’t contain them in any ordinary data types like a long integer. Use the power of Java’s BigInteger class and solve this problem.

Input Format

There will be two lines containing two numbers, a and b.


a and b are non-negative integers and can have maximum 200 digits.

Output Format

Output two lines. The first line should contain a+b, and the second line should contain a*b. Don’t print any leading zeros.

Sample Input


Sample Output



1234+20 = 1254
1234*20 = 24680
