   int i,j,k,l,n,m,T,a;

   char str[100],str1[100],str2[100];

   scanf("%d",&T);

   for(a=1;a<=T;a++)

   {

       scanf("%s",str);

       scanf("%s",str1);

       i = strlen(str);

       j = strlen(str1);

       if(i>=j)

    {

       for(k=0,l=0;k<2*j;k++,l++)

       {

        str2[k] = str[l];

        k++;
