490 - Rotating Sentences

[uvasarker]

Hi brianfry713,
Thank you very much for kindly help.
Now, it's still WA. Please, tell me where is the problem in my code. Here is my modified code.

Code: Select all

#include<stdio.h>
#include<string.h>
int main()
{

	while(true)
	{
	char s1[101]={'\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0'};
	char s2[101]={'\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0','\0'};
		int max,len1,len2;
			gets(s1);
			len1=strlen(s1);
			if(s2[0]=='\0' && s1[0]!='\0')
			{
				gets(s2);
				len2=strlen(s2);
			}
			if(s2[0]=='\0' && s1[0]=='\0') break;
			if(len1>len2)
			{
					max=len1;
			}
			
			else if(len2>len1)
			{
					max=len2;
			}
			else
					max=len1;
					
					
			int fag=0;
			for(int i=0 ; i<max ; i++)
			{
				printf("%c%c\n",s2[i],s1[i]);
				//if(i<max-1) printf("\n");
				fag++;
			}

			if(fag!=0)
			{
					for(int i=0 ; i<max ; i++)
					{
							s2[0]='\0';
					}
			}

	}
	return 0;
}

You're still assuming there are always two sentences, there could be up to 100, each of length up to 100. You also can't print the null characters at the end of a line, those should be spaces.

Try this input at http://www.uvatoolkit.com/problemssolve.php
Sentence one.
Sentence two is longer.
Shorter.

plz help, i don't know why i always get Runtime Error!plz help me,thanks.
and this is my code:

#include <iostream>
#include <stdio.h>
#define R 100
#define L 100
using namespace std;
int main()
{
freopen("490.txt","r",stdin);
char rot[L][R];
int n=0;
for(int i=0;i<100;i++)
for(int j=0;j<100;j++)
rot[j]='\0';
while(gets(rot[n]))
if(n<100)
n++;
for(int i=0;i<100;i++)
{
for(int j=0;j<n;j++)
if(rot[j]!='\0')
{
cout<<rot[j];
if(j==n-1)
cout<<endl;
}
else continue;
}
return 0;
}


and the 490.txt is:

Rene Decartes once said,
"I think, therefore I am."

[brianfry713]

Read the input from stdin, not a file.

[wz0o0zw]

Read the input from stdin, not a file.

#include <iostream>
#include <stdio.h>
#define R 100
#define L 100
using namespace std;
int main()
{
char rot[L][R];
int n=0;
for(int i=0;i<100;i++)
for(int j=0;j<100;j++)
rot[j]='\0';
while(gets(rot[n]))
if(n<100)
n++;
for(int i=0;i<100;i++)
{
for(int j=0;j<n;j++)
if(rot[j]!='\0')
{
cout<<rot[j];
if(j==n-1)
cout<<endl;
}
else continue;
}
return 0;
}

When I submit,i don't use "stdin" or "490.txt", i just use the codes above. But always i get Runtime Error,and i really don't understand.

[brianfry713]

This doesn't match the sample I/O.

[@ce]

Getting correct for sample input but getting WA...plzz help me find the error in my code.

Code: Select all

AC

[brianfry713]

Try the sample I/O again.

[@ce]

I am still not finding anything wrong

Input

Code: Select all

Rene Decartes once said,
"I think, therefore I am."

Output generated by my code:-

Code: Select all

"R
Ie
 n
te
h 
iD
ne
kc
,a
 r
tt
he
es
r 
eo
fn
oc
re
e 
 s
Ia
 i
ad
m,
.
"

[brianfry713]

Your problem might be that arr is uninitialized and then you check it for '\0'. On my machine (and possibly the judge's) that gave different results.

[@ce]

@brianfry....java version of the same code is also giving WA...neither i could correct the above C++ code

Code: Select all

AC

[brianfry713]

For your JAVA code, try the input:

Code: Select all

"I think, therefore I am."
Rene Decartes once said,

Output should be:

Code: Select all

R"
eI
n 
et
 h
Di
en
ck
a,
r 
tt
eh
se
 r
oe
nf
co
er
 e
s 
aI
i 
da
,m
 .
 "

There should be a newline at the end of the last line.

I'm having the same problem. I can't seem to see what's wrong with my output. Please help.

Code: Select all

#include <stdio.h>

int main(){
	char input[100][100] = {'\0'};
	int counter[100] = {0}; 
	char ch;
	int a = 0;
	int b = 0;
	int c = 0;
	int h;
	int i;
	int nos = 0; 
	int high = 0; 
	
	while (scanf ("%c", &ch) != EOF) {
		if (ch != '\n') {
			
			if (ch != '\t'){
				input[a][b] = ch;
				b++;
			}
			
		} else {
			counter[c] = b;
			
			if (high <= b) {
				high = b; 
			}
			
			c++;
			b = 0;
			a++;
			input[a][b] = ch;
		}
		nos = a;
		
	}
	
	a = nos - 1;

	for (h = 0;h < high;) {
		for (i = a; i >= 0; i--) {
			printf("%c", input[i][h]);
		}
		printf("\n");
		h++;
	}
	return 0;
}

[brianfry713]

For the sample input, you're printing null characters at the end of the last two lines.

Guru
Please check.......Why W A?

Code: Select all

#include <cstdio>
#include <cstring>
#include <string>
using namespace std;
int main()
{
	char in[101][110], s[101];
	int len[101], ln, l=0, maxx=0;
//	freopen("490.txt","r",stdin);
//	freopen("490_OUT.txt","w",stdout);
		while(gets(s))
		{
			ln=strlen(s);
			len[l]=ln;
			if(ln>maxx) maxx=ln;
			for(int i=0 ; i<ln ; i++)
				in[l][i]=s[i];
			l++;
		}

            for(int j=0 ; j<maxx ; j++)
            {
				for(int i=l-1 ; i>=0 ; i--)
				{
				    if(in[i][j]!='\0')
                        printf("%c",in[i][j]);
				}
				printf("\n");
            }

	return 0;
}
