A few of us successfully passed z-ioi2 task in training section by printing nothing but zeros. There's clearly something wrong with it.
Furthermore, it's impossible to read all input and print the output while flushing after every line, which is necessary before you can read next line. I fail to see how can that happen? By now we got used to tight time limits, but this is rather extreme. I think all the zeros in early grading were a good enough warning!
There seems to be a checker program grading this task and printing zeros passes. Even winning solution isn't flawless. It can be challenged by:
login 1 ... 8
submission 1 1 50
submission 2 1 48
submission 3 1 48
In my opinion correct solution would be 0 1 2. Checker needs fixing and a rejudge would be nice.
I realize it's a lot of work to organize all those competitions but maybe decrease the quantity and increase the quality of them?
Almost every competitons starts with an hour delay, there are 3 or more gradings at the end, outputs are wrong, graders for interactive tasks are behaving weird etc. Structure of test cases is a disaster so final scores are either 100 or 0 and we have a bunch of ties. There was a lot of working solutions for lets say z-nails and z-redblue which scored so poorly that it was embarrassing.
There's a lot of nice tasks and competitons on z-training and it would be a shame to lose all this on account of previously mentioned problems.
