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

Code: Select all

#include<cstdio>
#include<cstdlib>
#include<cmath>
#include<cstring>
#include<iostream>
#include<algorithm>

using namespace std;

int main()
{
    char arr[100][101];
    int i = -1, max = -1;
    while(gets(arr[++i]))
    {
          int l = 0;
          while(arr[i][l++] != '\0');
          if(l> max)
          max = l;
    }
    for(int p = 0; p<max;p++)
    {
            for(int q = i; q>=0; q--)
            {
                    if(arr[q][p] != '\0')
                                 printf("%c", arr[q][p]);
            }
            if(p != max-1)
            printf("\n");
    }
    //system("pause");
}

Try the sample I/O again.

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

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.

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

Code: Select all

import java.util.Scanner;
class Main
{
   public static void main(String[] args)
   {
      Scanner in = new Scanner(System.in);
      String arr[] = new String[100];
      int i = -1, max = -1;
       while(in.hasNextLine())
       {
          arr[++i] = in.nextLine();
          int l = arr[i].length();
          if(l > max)
             max = l;
       }
       for(int p = 0; p<=max-1;p++)
       {
               for(int q = i; q>=0; q--)
               {
                       if(arr[q].length() > p)
                           System.out.print(arr[q].charAt(p));
               }
               if(p != max-1)
                  System.out.println();
       }
   }
}

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;
}

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

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

hi! are you referring to the first sentence? since it has lesser characters it prints null characters. should it print a space? I edited my last code so it will print a space. so i added this code. but I still get a wrong answer.

Code: Select all

for (j = 0; j < c; j++) {
      temp = counter[j];
      if (high > temp) {
         min = high - temp;
         for (k = min; k >= 0 ;) {
         Tmin = temp+k;
         input[j][Tmin] = ' ';
         
         k--;
         }
      }
   }

[brianfry713]

There should be spaces, not null characters. Post your full code.

[xtine.m]

Here's my full code:

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 j;
   int k;
   int temp;
   int min = 0;
   int Tmin = 0;
   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;
      
   }
   
   for (j = 0; j < c; j++) {
      temp = counter[j];
      if (high > temp) {
         min = high - temp;
         for (k = min; k >= 0 ;) {
         Tmin = temp+k;
         input[j][Tmin] = ' ';
         k--;
         }
      }
   }
   printf("\n");
   a = nos - 1;
   
   for (h = 0;h < high;) {
      for (i = a; i >= 0; i--) {
         printf("%d", input[i][h]);
      }
      printf("\n");
      h++;
   }
   return 0;
}

Line 58 should be %c not %d.

What's wrong??
My code :-

Code: Select all

#include<cstdio>
#include<cstdlib>
#include<cmath>
#include<cstring>
#include<iostream>
#include<algorithm>

using namespace std;

int main()
{
    char arr[100][101];
    int i = -1, max = -1;
    for(int f = 1;f<100;f++)
            arr[f][0] = '\0';
    while(gets(arr[++i]))
    {
          int l = 0;
          while(arr[i][l++] != '\0');
          if(l> max)
          max = l;
    }
    for(int p = 0; p<max;p++)
    {
            for(int q = i-1; q>=0; q--)
            {
                    if(arr[q][p] != '\0')
                                 printf("%c", arr[q][p]);
                    else
                        printf(" ");
            }

You're printing an extra line at the end with two spaces.
