help...

i've known the answer about it.
i've never thought about the condition of a string null....

[cpp]
void readData()
{
while(infile>>a>>b)
{
outfile<<maxCommonString()<<endl;
}
}

int maxCommonString()
{
int i,j;
int m=a.size();
int n=b.size();
for(i=0;i<up;i++)
for(j=0;j<up;j++)
c [j]=0;
for(int i=1;i<=m;i++)
c [0]=0;
for(int i=1;i<=n;i++)
c[0] =0;
for(i=1;i<=m;i++)
for(j=1;j ...

who can prove the dynamic programming accuracy...

method...
who can tell me...
a bit of thanks...
