Здравейте!

Моля за съдействие. Решавам тук една задача - https://judge.softuni.bg/Contests/Practice/Index/978#13 .

Zero тестовете ми са ок. А всички останали се провалят.

Гледах, гледах. Не мога да открия, къде е евентуално грешката.

Прилагам и сорса. При мен се компилира ок. И изглежда ок. Измерил съм и колоните и редовете. Верни са.

Поздрави и благодаря предварително!
