I know My Algorithm is right, Then Why wrong answer

Code: Select all

Thanks Sohel. I forget the basic rules of Checking Input range.
Code Remove After A/C


[sohel]

What does your program output if the input is 0?
Hint: When you get WA in a problem, try to check the extreme cases first( In this case 0 and 1000000000)

Can Someone Help me to determine what is wrong with my code... I have tested several case...

Code: Select all

Code Removed After AC....

I didn't think of the out put 0 when the case is 0...

[ratul.i]

Can anyone please tell me why I get runtime error for this code:

Code: Select all

#include<stdio.h>

void reverse(char *num, int count)
{
    while(count>=0)
    {
        printf("%c",num[count]);
        count--;
    }
}

int main()
{
    long int a;

    while(1)
    {
        scanf("%ld",&a);

        if(a<0)
            break;
        else if(a==0)
            printf("0\n");
        else
        {
            char *c; int i=0;
            while(a>=1)
            {
                long int x = a%3;
                c[i]=x+'0';
                a /= 3;
                i++;
            }
            reverse(c, i-1);
            printf("\n");
        }
    }

    return 0;
}

instead of

Code: Select all

char *c;

try

Code: Select all

char c[MAXSIZE];

Thnx, Thnx a lot brianfry713 ... Accepted

[Nahian37]

#include<stdio.h>
int main()
{
long n,i,j,a[50];
while(1)
{
scanf("%ld",&n);
if(n<=0) break;

for(i=0;n>0;i++)
{
a[i]=n%3;
n=n/3;
}
for(j=i-1;j>=0;j--)
{
printf("%ld",a[j]);
}
printf("\n");
}
return 0;
}
whats the problem with this code?

[brianfry713]

For input:

Code: Select all

0
-1

AC output:

Code: Select all

0

I've accepted this problem after 3 times compiler error.But i can't find out the problem why the code is compiled error. For this I ignore the string.h function and do the task manually and got accepted . But still now I am in fix why I can't use strrev() function ? my previous code given below:

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

int main ()

{
char str [50];
int n,i;
scanf ("%d",&n);

while (n>=0){

i=0;
if (n==0){
str[i]=0;
str[i++]+=48;
}

while (n!=0){
str[i]=n%3;
str[i++]+=48;
n/=3;
}
str[i]='\0';

printf ("%s\n",strrev(str));
scanf ("%d",&n);

}
return 0;
}

[brianfry713]

strrev isn't supported in the judge's compiler.
