Скачать или смотреть Challenge 97: Summation Manipulation

Since I will be out of town for the next two to three weeks, I decided to postpone the next challenge problem to either July 10 or 17. I sincerely apologize for the delay.

Congratulations to Minh Cong Nguyen, Azzam Labib, Serengeti Ghasa, Jevon Shanahan, scaryowl007, Nicola C, Sonal Kumari, Mokou Fujiwara, Bintang Alam Semesta W.A.M, and José Luis Hablützel Aceijas for successfully solving the last challenge question! Minh Cong Nguyen was the first person to solve the problem.

This challenge problem and solution were inspired by Yassine Zaoui's proposal.
