For minimum blocks, make sure the blocks viewed from front and right are same, and make the cross point shared by front view and right view. For example: 7 3 0 2 3 5 8 1 8 1 4 1 1 0 6 8 pairs to 8, 1 pairs to 1, 0 pairs to 0 and remains have no pair, so they should be placed singlely, so total minim...

Another problem tricky float point number involved.

The problem statement is not so clear.

An interesting problem!

The test data on uDebug end with end of line instead of 0, beware of it.

The test data on uDebug: 31 9 5 8 2 1 7 7 11 3 6 5 4 9 10 5 2 1 5 3 9 7 16 3 11 2 7 3 4 8 5 10 7 8 3 7 4 2 3 9 10 2 5 3 25 1 7 7 7 7 8 8 8 8 9 9 9 9 10 10 10 10 11 11 11 11 10 11 3 5 4 3 2 9 6 10 10 6 2 7 3 4 7 4 5 3 2 4 3 2 3 10 11 3 5 4 3 2 9 6 10 10 6 2 7 3 4 7 4 5 3 2 4 10 11 3 5 4 3 2 9 6 10 10...

The judge of this problem need to fix, otherwise one would hard to get AC on first try.

The test data on uDebug contains: but the problem statement said that '-' is not a valid character, you should ignore input like this.

(1)The outputs of two consecutive cases will be separated by a blank line.
You print a blank line before first test case.
(2) and there is a blank line after each separate waveform, excluding the last one.
Check you output again, you should get AC.

For checking whether you use tow queue on elevatoror not. Input: C 15:00:00 0201 15 0301 20 0 D 15:00:00 0205 10 0 . ACed putput: C 15:00:00 15:00:30 Entry 15:00:30 15:01:00 Stay in elevator 15:01:00 15:01:10 Transfer from elevator to room 0201 15:01:10 15:01:25 Stay in room 0201 15:01:25 15:01:35 T...

The solution on uDebug seems have some problem, it couldn't get right output for input: the output of uDebug solution: it is wrong obviously.

For guys who want to solve this problem: (1)family name contain none space. (2)there are test data which some children's age are same but with difrrent birthday, you should choose the "max" birthday as youngest, for example, there are three children with birthday(in real life, it seems impossible fo...

I dont't think so, my AC solution assumes that there is no other commands rather than U, D, A, X.

The problem statement of PDF version is bad, not clear enough.

For WA, try input: output: by the way, trim the leading and tailing space(Maybe the input of judge contain non tailing space). Use regex for this problem is easy.
