UVa 713: Adding Reversed Numbers is a straight-forward problem that can be solved using an ad-hoc algorithm. We have discussed a similar problem in a previous blog-post. However, this problem imposes following additional constraint—numbers will be at most 200 characters long--which necessitates the use of BigInteger. Following Java code shows such an ad-hoc algorithm that solves this problem by considering the stated constraints.
