Tomasz Idziaszek - Booklet with solutions of past IOI problems
Tomasz Idziaszek is involved with the competitive programming community since 2002, first as a participant in programming contests, and next as an organizer of such events. In the following video, Tomasz will describe the IOI 2018 booklet with information on all six problems from IOI 2018 - containing detailed solutions and source code; in addition to discussing the task Mechanical Doll. This booklet is incredibly useful, as most reviews and official solutions to IOI problems are quite sketchy and don't contain any source code.
The project was partially funded by the IOI, as it was selected in the recent "Call for projects" officially published on the IOI website. The actual booklet can be found here: https://ioinformatics.org/files/booklet-ioi2018.pdf
