My program:

#include<stdio.h>
long n9,n;
int a,b;
void main(void)
  {
    int i,j,l;
    scanf("%ld",&n);
    n9=0;
    l=-1;
    for (i=0;i<n;i++)
      {
    scanf("%d %d",&a,&b);
    if (a+b==9) n9++;
    if (n9==0)
      {
        if (l!=-1) printf("%d",(a+b)/10+l);
        if (l==-1 && a+b>9) printf("%d",(a+b)/10);
        l=(a+b)%10;
      }
    else if (n9!=0 && a+b<9)
      {
        printf("%d",l);
        for (j=0;j<n9;j++) printf("9");
        n9=0;
        l=a+b;
      }
    else if (n9!=0 && a+b>9)
      {
        printf("%d",l+1);
        for (j=0;j<n9;j++) printf("0");
        n9=0;
        printf("%d",a+b-10);
        l=-1;
      }
      }
    if (n9!=1) for (i=0;i<n9;i++) printf("9");
    if (l!=-1) printf("%d\n",l);
    if (n==0) printf("%d\n",0);
  }

It is writed by C++,and got WA.
If there is some special test data makes my program got WA.May I have
it? Thank you!

Try these tests :

1 + 8
2 + 7
14 + 5
46 + 3
58 + 1
.
.
.
.
and so on .

If you still get WA send me an email . ciutu@go.ro
