Java BigInteger HackerRank Solution

Hello Programmers, In this post, you will know how to solve the Java BigInteger HackerRank Solution. This problem is a part of the HackerRank Java Programming Series.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Java BigInteger HackerRank Solutions

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.

Constraints

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

1234
20

Sample Output

1254
24680

Explanation

1234+20 = 1254
1234*20 = 24680

        sum = sum.add(a);
        sum = sum.add(b);
        product = a.multiply(b);
