Re: 434 - Matty's Blocks

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...

Re: 444 - Encoder and Decoder

The test data on uDebug contains:

Code: Select all

One is to write an encoder-decoder program here.
but the problem statement said that '-' is not a valid character, you should ignore input like this.

Re: 488-Triangle wave (continuously getting presentation error)

(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.

Re: 370 - Bingo

The solution on uDebug seems have some problem, it couldn't get right output for input:

Code: Select all

1 1 1 1 1
1 0 0 0 1
1 1 1 1 1
1 0 0 0 1
1 1 1 1 1
1
0
the output of uDebug solution:

Code: Select all

No BINGO on this card.

it is wrong obviously.

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

Re: 325 - Identifying Legal Pascal Real Constants

For WA, try input:

Code: Select all

000040040.001200E-000000123
0e-0
*
output:

Code: Select all

000040040.001200E-000000123 is legal.
0e-0 is legal.
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.
