UVa 136. Ugly Numbers

This blog-post is about  UVa 136: Ugly Number, a trivial, but interesting UVa problem. The crux involves computing 1500th Ugly number, where a Ugly number is defined as a number whose  prime factors

UVa 371. Ackermann Function

The underlying concepts of UVa 371: Ackermann Functions  have been discussed in great details in our post of Collatz problem. In this post, we simply outlines an ad-hoc algorithm as a solution to

UVa 713. Adding Reversed Numbers

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
