1. a) Unknown because j is not initialized

   b) j= 5


2. a) k modulus 2 = 0, j= 0
      k modulus 2 = 1, j= 1
      k modulus 2 = 0, j= 0
      k modulus 2 = 1, j= 1
      k modulus 2 = 0, j= 0

   b) Physics is fun

   c) k= 81; n = 8
      k= 64; n = 7
      k= 49; n = 6
      k= 36; n = 5
      k= 25; n = 4
