I'm using LCS here but it doesn't work. WHY??

[c]#include <stdio.h>

int main(void)
{
int common[101][101];
int a[101],b[101];
int i,j,m,n, counter = 0;

scanf("%d%d",&n,&m);
while((n > 0) || (m > 0))
{
++counter;

for (i = 0; i <= 100; ++i)
for (j = 0; j <= 100; ++j)
common [j] = 0 ...

What is qrong with this code:::


[c]#include <stdio.h>

int main(void)
{
int i, n1, n2, temp, length;
int a1[20], a2[20];

while (1)
{
scanf("%d%d",&n1,&n2);

if ( (n1 == 0) && (n2 == 0) )
break;

for (i = 0; i <= 15; ++i)
{
a1 = 0;
a2 = 0;
}

i = 0;
temp = n1;

/* Put the digits ...
