The binary representations of the above numbers are given in the
following table:

     1  00001
     2  00010
     4  00100
    25  11001
    26  11010

So:

   Int1 = 25&1 = 00001 = 1
   Int2 = 25&2 = 00000 = 0
   Int3 = 25&4 = 00000 = 0
   Int4 = 26&1 = 00000 = 0
   Int5 = 26&2 = 00010 = 1
   int6 = 26&4 = 00000 = 0

If you are getting different values, then there is a problem.
