here is my sample code ples check whats my problem. i got WA.

#include<stdio.h>
#include<string.h>
#include<math.h>
char str[200],str1[100],del[100];
main()
{

	int i,a,b,c,data[50],j,k,sum;
	freopen("11398.in","rt",stdin);
	while(gets(str))
	{
		if(strcmp(str,"~")==0)
			break;
		strcpy(del," ");
		char *res;
		res=strtok(str,del);
		i=0;sum=0;
		while(res!=NULL)
		{
			strcpy(str1,res);
			if(strcmp(str1,"#")!=0)
			{
				a=strlen(str1);
				if(a==1)
					b=1;
				else if(a==2)
					b=0;
				else
				{
					c=a-2;
					for(j=0;j<c;j++)
					{
						data[i]=b;
						i++;
					}
				}
			}
			res=strtok(NULL,del);
		}
		k=0;
		for(j=i-1;j>=0;j--)
		{
			sum+=(data[j]*(int)pow(2,k));
			k++;
		}
		printf("%d\n",sum);
	}
}

is there any special input output.

Check your binary to decimal conversion. The bug is in there.

Is it possible that the input can be like this? :

Code: Select all

In my code it is not printing anything for this type of input ( just going to the newline).

If input can be like this, what would be the output? I am not sure why I am getting WA

?
Thanx in advance.

My Code (in JAVA)

Code: Select all

public class Main 
{	
    public static void main(String[] args) throws IOException 
    {
    	BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
    	String totalStr="";
    	String binaryVal="";
    	int flag=-1;
        while (true) 
        {
            String line = reader.readLine();
               
            if (line.equals("~")) 
            {
                break; // end of file reached
            }
            if ( line.charAt(line.length()-1) !='#')
            {
            	totalStr+=line+" ";
            }
            else
            {
            	totalStr+=line;
            	StringTokenizer t = new StringTokenizer(totalStr," #");
            	while(t.hasMoreElements())
            	{
            		String temp=t.nextToken();
            		
            		if(temp.length()==1)
            			flag = 1;
            		else if(temp.length()==2)
            			flag = 0;
            		else
            		{
            			int n= temp.length()-2;
            			
            			for(int i=0;i<n;i++)
            				binaryVal+=flag+"";
            		}	
            	} 
            	if (!binaryVal.equals(""))
            		System.out.println(Integer.parseInt(binaryVal,2));
            	//else
            		//System.out.println(flag);
            	
            	totalStr="";
            	binaryVal="";
            	flag=-1;
            }     
        }// End while         
    }// End main
} //@End Program
