to alu_mathics,
in my opinion your last example is not correct. The problem statement says that the length of the sum does not exceed M. As M is 1, the answer 17 should not occur!
Haven't been accepted yet, so I'm not 100% certain but that's how I understand that sentence.
Bye

You have work hard for a easy problem!
It is just adding , read two digit and add them if carry or if result of this two is greater then 9 then store 1 for next pair of digit . so its is as easy as primary calculation. Just use char string to store result (no need to use long array)
10013 Accepted (P.E.)

who can help me? Thanks
Code: Select all
# include <stdio.h>
int main()
{
long i,j,n,m;
int num[1000000][2];
scanf("%ld",&n);
for(i=0;i<n;i++)
{
getchar();
scanf("%ld",&m);
for(j=0;j<m;j++)
scanf("%d%d",&num[j][0],&num[j][1]);
for(j=m-1;j>=0;j--)
{
if(num[j][0]+num[j][1]>=10)
{
num[j][0]=num[j][0]+num[j][1]-10;
num[j-1][0]=num[j-1][0]+1;
}
else
num[j][0]=num[j][0]+num[j][1];
}
for(j=0;j<m;j++)
printf("%d",num[j][0]);
printf("\n");
printf("\n");
}
return 0;
}

Hi,
The problem statement says that there is a blank line between two cases...
... which means there is no line after the very last case.
A portion of your code
[c]
for(j=0;j<m;j++)
printf("%d",num[j][0]);
printf("\n");
printf("\n");
[/c]
The second newline is not always necessary..
change this part of your code to
[c]
for(j=0;j<m;j++)
printf("%d",num[j][0]);
printf("\n");
if(i<n-1)
printf("\n");
[/c]
Hope it helps.
Thanks

Don't work hard with PE code
I think One should not post their accepted code here

Probable you must not put a blank line after last case e.g printf("\n\n").
You can write in this way:
while(i < n)
{
/* ...... */
if(i == n)
printf("\n");
else
printf("\n\n");
}
Again P.E

I use your Techniq
"while(i < n)
{
/* ...... */
if(i == n)
printf("\n");
else
printf("\n\n");
}"
But Same P.E

Oh... I've forgot
Delete the line
printf("\n")
before while(i<n) from your source code and you'll get a clean AC.

lin [lg++] += car;
}
}
catch (IOException e)
