490 - Rotating Sentences

[assasin]

Do you think if(count[j]>len[j][0]) is ok?

What if count[j] = len[j][0]?
Reconsider this and I think you are done.

Good Luck

Thank You.....I got AC

I had the same problem, solution was allocate space for 101 sentences, not 100 like problem said.

[kaffir]

Could anyone help?
I think I satisfy the requirement.
But I always get WA
Thank you

Code: Select all

#include <iostream>
#include <cstring>
using namespace std;

int main()
{
	char input[101][101] = {'\0'};
	int totSen = 0, totRow = 0;
	int row = 0, col = 0;
	int maxLen = 0;

	while(!cin.eof())
	{
		cin.getline(input[totSen], 101);
		totSen++;
	}
	
	cout << endl;
	
	//Find the length.
	for(int i = 0; i < totSen; i++)
	{
		int len = strlen(input[i]);
		
		if(maxLen < len)
		{
			maxLen = len;
		}
	}
	
	while(row < maxLen)
	{
		for(col = totSen-1; col >= 0 ; col--)
		{
			if(input[col][row] != '\0' )
			{
				cout << input[col][row];
			}
			else
			{
				cout << ' ';
			}
		}
		
		cout << endl;
		
		row++;
	}

	return 0;
}

			}
		}
		
		cout << endl;
		
		row++;
	}

	return 0;
}

it is clear !
in the problem test case you have 2 sentences for rotating but the your counter is 3 and when you want to print them at the first column you print a blank sentence !
this line "for(col = totSen-1; col >= 0 ; col--)" must be changes to "for(col = totSen-2; col >= 0 ; col--)"....

how can i get through the judge ?? pls help me work this out.

Code: Select all

#include <iostream> 
#include <algorithm>
#include <vector>
#include <string> 
using namespace std; 

int main() 
{ 
	vector<string> buffer; 
	vector<string>::iterator itor ; 
	string str; 
	int count = 0; 
	while(getline(cin, str)) 
	{ 
		buffer.push_back(str); 
	} 
	count = buffer.size(); 
	reverse(buffer.begin(), buffer.end()); 
	while (true) 
	{ 
		for (itor = buffer.begin(); itor != buffer.end(); itor ++) 
		{ // first test the string 's for sure it is not empty
			if (itor->empty()) 
			{ 
				count --; cout << " "; 
				continue;
			} 
			cout.put(itor->at(0)); 
			itor->erase(0, 1); 
		} 
		cout << endl;
	 	if (count == 0) break; 
	}

Hi , I'm getting PE on this task , I tried with and without a newline on the end of the output , I've got trailing spaces , I just don't get it

Code: Select all

#include <iostream>
#include <string>
#include <algorithm>

using namespace std;

int main()
{
	int fld[350][350];
	for(int i=0;i<150;i++)
	    for(int j=0;j<150;j++)
	        fld[i][j]=' ';
	 int maxi=0,n=0;
	 string r;
	 while(!cin.eof())
	 {
			getline(cin,r);
			if(maxi<r.size())maxi=r.size();
			for(int i=0;i<r.size();i++)
			{
				fld[n][i]=r[i];
			}
			n++;
	 }
	 for(int j=0;j<maxi;j++)
	 {
		 for(int i=n-1;i>=0;i--)
		 {
				cout<<char(fld[i][j]);
		 }
		 cout<<endl;
	 }
}

I hope that somebody can help me

Hi, first of all with this problem I was confused about how to take the inputs. Finally I made up my mind to take all the inputs uptill the end of the file and then print them in the sequential manner told.

However, after doing so, I am getting WA.... Help me out here....

here's my code:

#include <stdio.h>
#include <string.h>

int main()
{
freopen("input4uva.txt","r",stdin);

char name[100][100];
char temp[100];

int i=0,j,k,l,max=0;

while (gets(temp)>0)
{
strcpy(name,temp);
l=strlen(name[i++]);

if (l>max)
max=l;

}

for (k=0;k<max;k++)
{
for (j=i-1;j>=0;j--)
printf ("%c",name[j][k]);

printf ("\n");
}



return 0;
}

[kawsar]

#include<stdio.h>
#include<string.h>

int main(){
char a[1000][1000], x[1000], c ;
int i=0, p=0, j, k, n ;

while (c = getchar ()) {
if (c == EOF)
return 0;
n = 0 ;

x[n++] = c ;

while((c=getchar()) != '\n')
x[n++] = c ;
x[n] = '\0' ;


if(strlen(x) > p)
p = strlen(x) ;

strcpy(a,x);
i++ ;
}


for(j=0; j<i; j++){
if(strlen(a[j]) < p){
n = strlen(a[j]) ;

for(k=n; k<p; k++)
a[j][k] = 32 ;
a[j][k] = '\0' ;
}
}


for(k=0; k<p; k++){
for(j=i-1; j>=0; j--)
printf("%c",a[j][k]);
printf("\n");
}
return 0;
}


i don't understand the, why i got WA.

[kawsar]

#include<stdio.h>

}


for(k=0; k<p; k++){
for(j=i-1; j>=0; j--)
printf("%c",a[j][k]);
printf("\n");
}
return 0;
}

I don't understand why i getting Wrong Answer every time.

Can anyone help me to find out the error of this problem... ???

[mustak0715]

when will be the input stops?
tell me.
my code....
#include<stdio.h>

if(strlen(a)<=1)
break;

i++;
break;

i++;
}
max=i;
int maxlength;
maxlength=strlen(a[0]);

for(i=1;i<max;i++)

You're assuming there are always two sentences, there could be up to 100. You also can't print an extra null character at the end of a line.

Post to an existing thread about a problem.
