BigInt problem: got Wrong Answer

I got wrong answer for this problem. My algo and the implementation with my Big Int seems correct to me.
For checking the values I printed all the cases in a file.
Can anyone point me which case I am printing wrong answer:

Code: Select all

n = 100 output is: 896519947090131496687170070074100632420837521538745909320

Thanks for the help.

I realised my mistake.
Product of n digit number with another n digit number can go upto 2n digit number.
I should have taken this into consideration.
