thank you!!

void main()
{
long int v,i;
double count,m,z;
char tran[12];
while(gets(tran))
{
z=count=v=0;
if(!strcmp(tran,"-1"))
break;
if(tran[0]=='0'&&tran[1]=='x')
{
for(i=strlen(tran)-1;i>=2;i--)
{
m=pow(16,count);
if(tran=='F')
m=m*15;
else if(tran=='E')
m=m*14;
else if(tran=='D')
m=m*13;
else if(tran=='C')
m=m*12;
else if(tran=='B')
m=m*11;
else if(tran=='A')
m=m*10;
else
m=m*((double)tran-'0');
count++;
z+=m;
}
printf("%.lf\n",z);
}
else
{
v=atoi(tran);
printf("0x%lX\n",v);
}
}
}

Just consider this case:
0xB
0xC
whose output should be:
11
12
10473 : Output Limit Exceed

Hi.
I don't have any infinite loops in my code.. I don't understand the error...
Heres my code :
Code: Select all
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
int main() {
char line[1000];
char aux[1000];
char *lixo;
int i;
scanf("%s\n",line);
do {
if (atoi(line) != -1) {
if (line[0] == '0' && line[1] == 'x') {
strcpy(aux, line);
i = strtol(aux, &lixo, 16);
printf("%d\n", i);
}
else
printf("0x%X\n", atoi(line));
scanf("%s\n",line);
}
} while(atoi(line)!=-1);
return 0;
}
Input tested :
4
7
44
0x80685
0xABC
2748
0x1
0xABCDEF
123456
0x123456789
291
0x123
291
0xB
0xC
-1
Output :
0x4
0x7
0x2C
525957
2748
0xABC
1
11259375
0x1E240
2147483647
0x123
291
0x123
11
12
Can anyone see the problem?

Well u have a BIIIIIIIIIIIG infinite loop.....
well ur code really give me hard time brother....I should have seen it earlier....when I could not find any logical error....I get back to the problem description.....and u know it always help.....
and what I found is that the programme will be terminated by a negative decimal value not necessarily with -1 all the time....
so u should do: atoi(line)>=0 instead of doing atoi(line)!=-1 in both of the places....and ur code got Accepted when I changed it......R U HAPPY NOW?
Goodluck.....see u later on......

HI.
Tanks for replying.
In fact, i haven't notest that problem of the decimal integer
Tanks
I've tested it but now I got Wrong Answer
Code: Select all
(...)
if (atoi(line) >= 0) {
if (line[0] == '0' && line[1] == 'x') {
(...)
} while(atoi(line)>=0);
(...)
I think that the judge doesn't like me

Hey....come on.....
dont be so frustrated....
how did u submit ur code.....do u use somekind of mail service like yahoo or hotmail? may be thats the reason why u r getting WA.....
i just copy-paste ur code in the judge submitter and just changed the sign to (>=0) from (!=-1) and it got Acc again right now.
always use the submit-o-matic software in the main window " submit your code here " u will see it, never mail ur code and becareful about the correct problem number......10473
there cant be any other reason for ur WA...ur code is ok and got AC twice
(shall I submit it for u?
)

Hello Brother.....weeeell I got wrong answer this time
But I also found the error in ur new code....
well I told u to change >=0, not to put extra ' ;' in ur printf();
have a look u have extra semi colons in ur printf function, just before the '\n' and thats the reason for ur WA.....I dont know why u did it....but u know it happens sometimes, when things get wrong. But no matter never lose hope. I m in good form now-a-days. sometime it also happens to me.
your country will be proud of u if u dont lose confidence and keep trying no matter what happens......
I hope u get Ac this time, and if not, I will be back

I put the semicolon just to see if there was any garbage on the printf's and I forget to take it off!!
Accepted now

spaces.
The last two lines of the sample input contain the

it's horrible easy to solve this using C/C++
here's the part that shows advantage of C++;D
Code: Select all
if(strlen(line)>=3 && line[0] == '0' && line[1] == 'x') //then num is in hexdecimal system
{
line[0] = line[1] = ' ';
sscanf(line,"%x",&num);
printf("%d\n",num);
}
else //decimal system
{
sscanf(line,"%d",&num);
printf("0x%X\n",num);
}

Here is my code
I can compile it in GCC of Freebsd and devc
but why compiler error?
Code: Select all

string input;
int loc_x,loc_neg,d;

loc_neg=input.find("-",0);
loc_x=input.find("0x",0);
if(loc_neg!=string::npos) {
if(loc_x!=string::npos) {
istringstream(input) >> hex >> d;
cout << dec << d << endl;
}
else break;
}
else {
if(loc_x!=string::npos) {
istringstream(input) >> hex >> d;
cout << dec << d << endl;
}
else {
istringstream(input) >> d;
