The NameInput problem was featured in the TopCoder SRM 461 as the Division 2 hard problem, and was solved by only 13 competitors out of 1141. This SRM was possible thanks to dolphinigle, who gave five nice problems for free. Problem Statement [+/-] Show/Hide problem statement You want to input your name into your...
