865 - Substitution Cypher

[GVahe]

can anybody tell me where is the mistake in my program or
give me some inputs and outputs of an AC program
Here is my code
[pascal]
var i,j,k,l,n,m,p,r:integer;
a:array[#1..#255] of char;
c:array[#1..#255] of boolean;
s,t:string;
begin
readln(p);
readln;
for r:=1 to p do
begin
fillchar(a,sizeof(a),' ');
fillchar(c,sizeof(c),false);
readln(s);
readln(t);
writeln(t);
writeln(s);
l:=length(t);
for i:=1 to l do
begin
if s<>' ' then
a[s]:=t;
c[s]:=true;
end;
while not(eoln) do
begin
readln(s); l:=length(s);
for i:=1 to l do
if c[s] then write(a[s]) else write(s);
writeln;
end;
if r<>p then writeln;
end;
end.
[/pascal]

plz help me

Try the input / output that is below.
Please have in mind several things:

1) The first input text contains two lines
which seem like empty lines. That is why they
contain just spaces. Put in each of these
line 2-3 spaces. This may reveal a BUG in your
program like it did reveal one in mine.

2) In the second input the plaintext alphabet it:
aeoiu<space>. And the substitution
alphabet is AEOIUX so each space gets
substituted with an X.

3) Note also that my program gets Accepted P.E.
and not a clean Accepted. I normally do not work
more on a problem after I get Accepted P.E. I am
not a real contester, quite old for that

Shar's Birthday:
The birthday is October 6th, but the party will be Saturday,
October 5.  It's my 24th birthday and the first one in some
years for which I've been employed.  Plus, I have new clothes.
So I have cause to celebrate.  More importantly, though,
we've cleaned the house!  The address is 506-D Albert Street.
Extra enticement for CS geeks:  there are several systems in
the house, and the party is conveniently scheduled for 3 hours
  
after the second CSC programming contest ends (not to mention,
        
within easy walking distance)!

aeoiu 
AEOIUX
For each test case, the output must follow the description
below. The outputs of two consecutive cases will be
separated by a blank line.

[GVahe]

thanks, I get ACC
I think I was very tired when I was writing that program (so stupid mistake )

[Sedefcho]

Did you get ACC using my sample I/O?!

Your previoud POST is from Oct 23, 2004

I didn't believe you will read my post !!!

[Sedefcho]

Your PREVIOUS POST[color], I meant
is from Oct 23, 2004 [color] ?!

[Sedefcho]

Your PREVIOUS POST, I meant

[GVahe]

I don't see this problem after I that post, so when u reply I read it again, open my program and find the bug using your I/O.

P.S. maybe you get PE because ur program prints a line after last case.

[Anindya]

I am getting Wa on 865.
Can anyone give me some sample i/o?

[Anindya]

Pleasssssse help me on this problem.I am getting a lot of wa.
My code is given below:

Code: Select all

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<math.h>
//#define Long __int64
//#define Long long long
int main()
{
	int n,i,flag=1,j,printed=0;
	char alpha[30],plain[30],c;
	scanf("%d",&n);
	for(i=0;i<n;i++)
	{
		if(i)printf("\n");
		scanf("%s%s",alpha,plain);
		scanf("%c",&c);
		printf("%s\n%s\n",plain,alpha);
		while((c=getchar())!=EOF)
		{
			printed=0;
			if(c=='\n')
			{
				if(!flag)
				{
					printed=flag=1;
					break;
				}
				else
                                {
					flag=0;
					printf("%c",c);
					printed=1;
                                }
			}
			else flag=1;
			for(j=0;alpha[j];j++)
				if(alpha[j]==c)
				{
					printf("%c",plain[j]);
					printed=1;
				}
			if(!printed)printf("%c",c);
		}
	}
	return 0;
}

Please help me to find the errors or give some sample i/o.

[Anindya]

Pleasssssssssseeeeeeeee help me.I am getting consecutive WA's.
Give me some sample i/o or help me to find my errors.
Thanks in advance.

[shakil]

i also get WA. But why?? can any one give some sample input and output???

Your program is confusing and hard to debug (I tried, but couldn't find the bug).
How about using gets() instead of getchar() like below.
Then you don't need to do complexing things (flag, printed ..)

Code: Select all

while (gets(buf) && *buf) {
   for (i = 0; buf[i]; ++i)
       ....;
   putchar('\n');
}

WRONG ANSWER

Code: Select all

#include<stdio.h>
int main()
{
	char plain[60],subs[60],text[70];
	int n,vector[150],i,t=0;
	scanf("%d",&n);
	while(n--)
	{
		scanf(" %s %s",plain,subs);
		getchar();
		for(i=0;i<150;vector[i]=i,i++);
		for(i=0;plain[i];vector[plain[i]]=subs[i],i++);
		if(t)
			printf("\n");
		else
			t=1;
		printf("%s\n%s\n",subs,plain);
		while(gets(text)&&*text)
		{
			for(i=0;text[i];printf("%c",vector[text[i]]),i++);
			printf("\n");
		}
	}
	return 0;
}

In this problem, 'alphabet" means not only a .. z, A .. Z, but set of letters.
So there might be a case like below.

Code: Select all

1

abc,-= y89
1234567890
This is a test.

I confirm this by using assert(), which yield RE (Signal 6),

Code: Select all

for (i = 0; plain[i]; ++i)                                                              
   assert(isalpha(plain[i]) && isalpha(subs[i]));
