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

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.

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.
Code: Select all
000040040.001200E-000000123
0e-0
*
Code: Select all
000040040.001200E-000000123 is legal.
0e-0 is legal.
