Try this
Input:

Code: Select all

000 00 0 00 000 #
~

Output:

Code: Select all

2

Thanks all.

why!!!

000 is ignored (it's a valid input? doesn't matter...) RESULT = 0
00 FLAG = 0 RESULT = 0
0 FLAG = 1 RESULT = 0
00 FLAG = 0 RESULT = 0
000 push 3-2=1 digits of FLAG = 0 RESULT = 0

result = 0

I am very sorry.

000 00 0 00 000 #
~

Output:

Code: Select all

0

I updated the output.

Submit your code again.
I did not know that GNU C++ compiler supports and operator.

Code: Select all

while (cin >> block and block != "~")

is similar to

Code: Select all

while (cin >> block && block != "~")

Returning a value from int main() is a good practice.
You will get accepted.
May be you submitted wrong code before.
And don't forget to remove your code.

I changed "and" to "&&" and i got AC...

why?

I always used "and" in al my programs, and never I got any problem :?

you must get inputs by using either scanf("%s") or scanf("%c")
because input may be given in the following format

input:
0000 0 0000 00
000 0 0000 #

output:
27

may it helps you

thats not true.you can use gets to take input.because each block is seperated by a space.
so the judge input is

Code: Select all

look like
0000 0 0000 00(space here)
000 0 0000 #
not like
0000 0 0000 00(without space)
000 0 0000 #

and first block may contain more than two 0.so your code need to ignore it.and when there is a consequetive block of one and two zero,and then larger block,u should consider the last (one/two) no. zero block for the larger block.

can any one help why i am getting wa,

Code: Select all

#include<stdio.h>
#include<math.h>
int main()
{
char ch,f,ch1[100];
int i,j,len,sp,c,d,o=0;
double sum,sum1,k;
len=0;
sp=0;
j=0;
while(scanf("%c",&ch)==1){
if(ch=='0')
len++;
else if(ch==' ') {
sp++;
if(sp==1&&len>2)
o=1;
else if((len==1||len==2)&&sp%2!=0)
	{
c=len;
if(c==1)
f='1';
else
f='0';
	}
	else{
	d=len-2;
	for(i=0;i<d;i++)
	ch1[i+j]=f;

	j=i+j;
	}
len=0;

		}
else if(ch=='#'){
  if(o==1)
  sum1=0;
  else{
k=0;
for(i=j-1;i>=0;i--){

printf("%0.f\n",sum1);

}
else if(ch=='~')
break;
}

return 0;

 if(l==1)
 x=1;
 if(l==2)
 x=0;
 else
 {for(i=2;i<l;i++)
  v.push_back(x);}
 scanf("%s",a);}
int y=v.size();
double s,k;s=0;
for(i=y-1;i>=0;i--)
{k=pow(2,i);
 s+=v[i]*k;}
printf("%.0lf\n",s);}
return 0;}

Don't use doubles.
