10291 - Cut the Legs

Post by Caesum »

Can someone please clarify what this question means ? What exactly are the criteria for having a non-rocking table ? I mean a table with one short leg and 50 equal longer length ones will still rock if you push down hard enough.

The table should not rock without pushing, that means the table should be balanced and the surface of the table has to be parallel to the ground. You have to use your imagination what the criteria is that the table is balanced.

The problem description is really opaque. I didn't even realized it was such a problem in the contest!

HINT: It has something to do with gravity.

10291: cut the legs - lousy input format

Post by ggll »

Just FYI. While the problem states that
For each table, a line will give an integer t, between 3 and 50, indicating the number of legs on the table. t subsequent lines will give, in order around the table's circumference, the lengths of the legs in millimeters.
it doesn't mean that each line only has the length for one leg.
