This book is intended to be a tool for young students preparing for the Object Oriented Programming exam or for graduates preparing for an interview employment. The book contains issues from the LeetCode and PBInfo platforms. The titles of the problems were taken as they appear on the platforms with problems, only the statements were translated into Romanian. I have kept the issue title and the issue identifier from the platform of origin.
The book was produced during the academic year 2022-2023, initially intended for the students whom they guide to the specialization Economic Informatics within the Ștefan cel Mare University of Suceava.
