```这是我的程序，大牛帮忙看一下吧！我实在不知道哪个地方错了
#include <stdio.h>
#include <string.h>

int  abs(int m)
{
if (m>=0)   return m;
else        return -m;
}

int  main()
{
int   i,j,k,n,a,b,t,ts,num[11],min,flag;
char  ch;
scanf ("%d",&ts);
for (t=0;t<ts;t++)
{
memset(num,0,sizeof(num[0]));
n=2;
scanf("%d%d",&num[0],&num[1]);
while(scanf("%c",&ch),ch!='\n')
{
scanf("%d",&num[n]);
n++;
}
if (n%2==1)
{
a=0;
b=0;
if (num[0]==0)
{
num[0]=num[1];
num[1]=0;
}
for (i=0;i<=n/2;i++)        a=a*10+num[i];
j=n/2;
for (i=n-1;i>j;i--)         b=b*10+num[i];
printf ("%d\n",a-b);
}
else
{
min=10;
for (i=0;i<n-1;i++)
if (abs(num[i+1]-num[i])<min)
min=abs(num[i+1]-num[i]);
flag=1000000;
for (i=0;i<n-1;i++)
{
a=0;
b=0;
if (abs(num[i+1]-num[i])==min)
{
a=num[i];
b=num[i+1];
j=1;
for (k=n-1;k>=0;k--)
{
if (k!=(i+1)&&(k!=i))
{
j++;
a=a*10+num[k];
}
if (j==n/2) break;
}
j=1;
for (k=0;k<n;k++)
{
if (k!=(i+1)&&(k!=i))
{
j++;
b=b*10+num[k];
}
if (j==n/2)  break;
}
}
if ((flag>abs(a-b))&&(abs(a-b)!=0))
flag=abs(a-b);
}
printf ("%d\n",flag);
}
}
return 0;
}
