Hello turuthok,

i failed to describe it,,

i meant, instead of this code:[c]while(gets(a))
{
...
...
.....printf("%c",a);
}
printf("\n");
[/c]

we can also use this...[c]while(scanf("%s%c",a,&ch)==2)
{
...
...
...
.....prinft("%c",a);
}
printf("%c",&ch);[/c]

is it clear now???

Sajid, forgive me ... but I still cannot see how you handle multiple spaces between words using your method of "%s%c" stuff ...

If it works, ... I'm happy for you

Regards,

-turuthok-

turuthok, look ...

[c]while(scanf("%s%c",a,&ch)==2)
{

}
[/c]

here, the single word is stroed in a[] and the next non-alphabet(digit, space, newline etc.) is stored in ch.
and u can do the loop word by word and after completing each loop, jst print the ch variable.. which stored a non-alphabetic chanracter..
and that's it... It works in my program.It's cute technic, isn't it?

But my program still WA.......................

It's my best, baby! Yet not AC... This time a <0.353 sec> WA.
More trick(s) missed?
[cpp]#include <stdio.h>
#include <string.h>

char str[1000000],word[1000000];
long len,i,j,k;

void main ()
{
while (gets(str))
{
len=strlen(str); j=-1;
for (i=0;i<=len;i++)
{
if ((str>=65 && str<=90) || (str>=97 && str<=122)) {j++; word[j]=str;}
else
{
if ((str[i-1]>=65 && str[i-1]<=90) || (str[i-1]>=97 && str[i-1]<=122))
{
if (word[0]=='a' || word[0]=='e' || word[0]=='i' || word[0]=='o' || word[0]=='u' || word[0]=='A' || word[0]=='E' || word[0]=='I' || word[0]=='O' || word[0]=='U')
{
printf ("%say",word);
}
else
{
for (k=1;k<=j;k++)
{
printf ("%c",word[k]);
}
printf ("%cay",word[0]);
}
for (k=0;k<=j;k++)
{
word[k]='\0';
}
j=-1;
}
if (str!='\0') printf ("%c",str);
}
}
printf ("\n");
}
}[/cpp]

I think, u still cant get..

ok, lets compare the following two almost the same programs.

Using gets()...

[c]char a[100];
int i;
while(gets(a))
{
for(i=0;a;i++) printf("%c",a);
printf("\n");
}[/c]

Using scanf()...

[c]char a[100],ch;
int i;
while(scanf("%s%c",a,&ch)==2)
{
for(i=0;a;i++) printf("%c",a);
printf("%c",ch);
}[/c]

Get it now???

To Sajid,
your code it has a bug.....since scanf ignores white spaces....your module wont stop until it reached end of file.
Meanwhile, gets function stops when it encounters '\n' or carriage return '\r'. So....your code cannot get one line at a time. Ex :

Input :
What if the input is more than one line?
Like this sample

Using your module.... string a will contain "sample".
But using gets function, a contain "What if the input is more than one line?"
Then....the program starts to process the string to get the proper output
before gets another line.

Hope i'm right,
Nick

To Nick,
Yes.. i m so sorry that my code has some bugs which i overlooked...

thanx nick..

Turuthok,sorry, my code will not work with the above input..
sorry for that....

Sajid, don't worry about it ...

I hope you'll get this problem AC-ed soon ...

Hunter, ... try this input:
-turuthok-

I have tested and tried the code. It does work. Maybe its the compiler that you are using to compile it. I am using Microsoft Visual C++ .NET. When I submit this code to the online judge I get a WA, when I change the array length to 1000000 and not a TLE or RTE, which might suggest what you are saying. I am sorry for writing the wrong array length. Just for clarification, arent you supposed to print out the digits or any other characters before and after the words?

(non-words should be output exactly as they appear in the input):

Thanks for replying,
Aditya

I don't understand..! Shouldn't it result:

To Sajid:
Of course, it's ANSI standard...
in many problems, you will get RTE if you use smaller array

Razib

I don't like this!!! This prob. keeps me WA for weeks...!!
I've handled the "abc123def" input to result "abc123defay". Is it correct?!
Few I/O cases follow up: What they should result?
Do the "consecutive sequence of letters (upper and/or lower case)" takes alphaNUMERIC characters?

at last i got AC ...

thanx to all.. specially Turuthok.
