OJ Board

I don't have conio.h on my system. Post the code you'd actually submit, not one with "Enter the number".

Here's my java code I don't why getting RunTime Error. Can any one help me ? Thanks in advance ......


import java.math.BigInteger;
import java.util.Scanner;


public class Main {

public static boolean Palindrome (BigInteger num){

String str =num.toString();
int lengthNum =str.length()-1;
int length =0;
boolean palindrime =true;

while (length<lengthNum){
if (str.charAt(length++) !=str.charAt(lengthNum--)){
palindrime =false;
break;
}
}
return palindrime;
}

public static void main (String[] args){

Integer num, reverse = 0, t, cnt =0;
BigInteger result =BigInteger.ZERO;
boolean palindrime =false;
Scanner scan =new Scanner (System.in);

t =scan.nextInt();

while ((t--)>0){

num =scan.nextInt();
while (!palindrime){
String str =num.toString();
StringBuffer buffer =new StringBuffer (str);
buffer =buffer.reverse();
reverse =Integer.parseInt(buffer.toString());

cnt++;
result =BigInteger.valueOf(num+reverse);
palindrime =Palindrome (result);
num =result.intValue();
}
System.out.println (cnt+" "+result);
cnt =0;
palindrime =false;
}
}
}

Try input 4000000000, output should be 1 4000000004.

Here I'm getting WA. Can any one help me ?please please please.

post your full code including your main function. Use the code blocks.

please help me. i'm getting wa.



#include<stdio.h>
#include<stdlib.h>

int main()

}
}

return 0;

}

{

{
j++;
ncount--;
}
else
return 0;

}

return 1;

}

Your pendulam function returns 1 for num=1021.

I get Runtime Error for this code. Everything seems to work fine when I run it from Code Blocks.
Help me out please.

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

char a[10],b[10];

int palindrome()
{
int i,j;
int l=strlen(a);

if(l%2==0)
for(i=0, j=l-1;i<=l/2;i++, j--)
{
if(a!=a[j]) return 0;
}

else
for(i=0, j=l-1;i<l/2;i++, j--)
{
if(a!=a[j]) return 0;
}

return 1;
}

int main()
{

int i,j,l,count;
int test;
long long int temp;


//freopen("test.txt", "r", stdin);

scanf("%d", &test);

while(test--)
{
count=0;
scanf("%s", &a);
while(1)
{

l=strlen(a);

for(i=l-1, j=0;i>=0;i--, j++)
{
b[j]=a;
}
b[l]='\0';

temp=atoll(a)+atoll(b);

sprintf(a, "%lld", temp);

count++;


if(palindrome()==1)
{
printf("%d %s\n", count, a);
break;
}


}
}

return 0;
}

Change line 5 to:
char a[11],b[11];

My code generates all the correct outputs,.. still getting WA. Can anyone figure out where am I wrong.... Got that.. thanks brian fry. I didnt notice my first char is a null. cmd in windows showed that as space :/

Doesn't match the sample I/O. You're missing the space after the number of iterations.

#include<stdio.h>
#include<string.h>
int main()
{
char x[500];
char temp[500];
int count=0,i,j,jj;
scanf("%d\n",&j);
for(jj=0;jj<j;jj++)
{
gets(x);
strcpy(temp,x);
strrev(temp);
count=0;
while(strcmp(temp,x)!=0)
{
char hasil[100];
int counter[100]={0};
hasil[0]='0';
for(i=strlen(temp)-1;i>=0;i--)
{
hasil[i+1]=x-48+temp-48;
if(hasil[i+1]>=10)
{
hasil[i+1]%=10;
counter++;
}
hasil[i+1]+=48;
}
for(i=strlen(temp)-1;i>=0;i--)
{
hasil+=counter;
}
hasil[strlen(temp)+1]='\0';

if(counter[0]==0)
{
for(i=0;i<=strlen(temp);i++)
{
hasil=hasil[i+1];
}
}
strcpy(x,hasil);
strcpy(temp,x);
strrev(temp);
count++;
}
printf("%d %s\n",count,x);
}
return 0;
}

all test case i use got correct answer
please help me

You can click "My Submissions" and see the reason for your compile error. You can't use strrev on this compiler.

Why WA? my code seems to give correct output for all possible input. please help!

Doesn't match the sample I/O.
