Clarifications

#	When?	Question	Answer
1	1 year, 9 months ago	General Frozen time	- During the last 60 minutes the standings is no longer updated, although each team continues receiving the judgements to their submissions. - The final results (including the verdicts during the frozen time) will be revealed 30 minutes after de contest ends.
2	1 year, 9 months ago	C - Computing Near-Death Experience The solution must exact?, I mean, is it missing at the output specifications "The solution would not change if the points were moved 10^-6 in every direction" or something like that? Great problemset :)	Yes, you can assume that the solution won't change if the points are moved 10^-6 units in any direction.
3	1 year, 9 months ago	G - Go Kill the Monsters should the result of m/2 be truncate or round?	The \|_ x _\| mathematical notation means floor of x.
4	1 year, 9 months ago	L - Luminaries Clarification(s) on Problem L	- Output is guaranteed to fit in 64-bit integers.
5	1 year, 9 months ago	J - Join the Game Clarification(s) on Problem J	- The output of the second test case should include a blank line; this does not appear on the printed version of the problemset, but it does appear correctly on MOG.
6	1 year, 9 months ago	K - Keyboard Patterns Clarification(s) on Problem K	- The output for the last sample test case output is incorrect. Correct output is on MOG. - Added rule: “To go to the next key in the pattern, the user MUST slide his finger in a straight line”. - Added to Hint: “In the fourth example, if the user wants to go from key 1 to key 3, he must go in a straight line passing through key 2, therefore the pattern 1→3→2 is impossible to achieve”.
7	1 year, 9 months ago	E - Enjoy the Chat Group Clarification(s) on Problem E	- The array of the third sample case should be sorted. On the printed version of the statement it is not, the correct version of this sample is on MOG.
8	1 year, 9 months ago	A - Again? Solving Queries? Clarification(s) on Problem A	It is guaranteed that all input elements are integers.
9	1 year, 9 months ago	General General clarifications	- Notice that there might be different time limits per language. Check the time limit hovering the click over (details) next to the Languages section on each problem. - It is recommended to use fast I/O to read the input and print the output. - During the real competition if the question (request for clarifications) can be answered by re-reading the statement the response will be "No Comments".
