Five Hard Problems with a Simple Solution

Authors: Marco Ripà

We present a collection of five nontrivial exercises in number theory (Questions 1—4) and graph theory (Question 5). These problems can be efficiently solved using insights and shortcuts derived from the author's previously published papers. This preprint invites readers to test their expertise in these fields and assess their ability to independently solve the proposed exercises. Detailed solutions are included.

Comments: 5 Pages. Revised version (v2): refined presentation and style, clarified proofs, results unchanged.
