In newer problems on CodeForces and other sites, I usually see multi-test inputs that say something like "it is guaranteed that sum of $$$n$$$ over all testcases does not exceed XXXXX".
I am unable to figure out how to implement such a generator in Polygon. Can someone tell me how exactly I should go about this?
1) generate k tests with n = bound / k
2) generate one big test and a lot of small tests
3) generate tests with n = random(1, bound — sum of generated n) until their sum exceeds bound
