Discussion of Problem 1290. Sabotage

Test case N=0 (WA2)
Posted by Aleksei Chernenkov 24 Jan 2022 12:35
Problem description is very unclear on what to do when N=0.

I believe that either
 * test case N=0 must be clarified or
 * lower bound of N must be set to 1.

Hint: In current test suite the correct answer for N=0 is empty output.
