706 - LCD Display

[afonsocsc]

Hello,
try this input:
10 99999999
10 12345678

[afonsocsc]

Hi,
I did a diff with your output and mine and here's the result:
Your program is printing one extra blank line in the beginning, and is adding one extra space at the end of each line.

Hope it helps

Why are you storing the input in an array?
If the input has more than 10 lines (excluding the last), your program will have an ArrayIndexOutOfBoundsException

You should process each line as you read it.

is there any wrong output?
is there something missing?

I would be very glad if a good soul would help me because I've been stuck with this problem for a long time

[Maniac]

for problems with the problemset, don't post here but at the forum-part specially meant for that. There you'll also probably find out about other peoples troubles with this problem etc. Good luck!

Hi try this out

here '*' means space

Code: Select all

your output:

3 0

*---
|***|
|***|
|***|
****
|***|
|***|
|***|
*---

my output:

3 0

*---*
|***|
|***|
|***|
*****
|***|
|***|
|***|
*---*


check out the last asteriks, u cant just keep it empty , u have to fill the whole size with space or either '|' or '-'

i hope u will pass PE this time......and u know how to modify ur code....

Goodluck :wink:

Hmm did what you said, but it still didn't work.

Hey thanks! It works on this judge but not the programming-challenges one. Haiz. The programming-challenges judge is so irritating.

[CodeMaker]

Well happy to hear that ur problem is solved....

I did not tried it in programming challenges judge.....but if the problem descriction is same then it should have worked......

but u can try one thing there......cut out newline after the last output. now question is how u will undestand which one is last input?.....

well there is a way, u can print newline before each output except the 1st one and thats not so hard, actually I solved it in this way at the 1st time and this judge gave me PE......then i print newline after each case and got Acc, so there is a possibility that the opposite happens in programming challenges judge.......but dont try anything else, because i dont think that will work

well, goodbye and goodluck.......

Hey thanks but it still doesn't work. I'm so frustrated.

Could you please help me with my code? The judge answered "WRONG ANSWER". I don't understand why.

Is there any special input present, what my code didn't consider?
I didn't consider NEGATIVE numbers
I didn't consider SIZE = 0
I didn't consider LEADING ZEROs.

This is my code

Code: Select all

//Wrong answer
#include<stdio.h>
#include<math.h>

char a[10][5][3]=
{
	//ZERO

You have to consider leading zeroes. If there is one or more leading zeroes, you have to show them in the output
