  Gray Code is Unit distance,Cyclic and Reflective.For one variable gray code is simply 0 and 1
  ,for two variables gray code is 00,01,11,10,if we observe the any two consecutive numbers there should be only one bit is changing so gray code is unit distance.For writing gray code for 2 variables first write graycode for 1 varible ( i.e 0 and 1) in vertically
  (Step1)
  0
  1
  gray code is reflective means write the mirror image of the above one
  (Step2)
  0
  1
  1
  0
  gray code is cyclic means for the above first half numbers attach 0(Step3)
  and remaing half numbers attach 1 (Step4)
  then it will give gray code for 2 variables.
  00
  01
  11
  10
  in the above step 1,2,3 and 4 represent in red ,green,blue and Pink colors consecutively.
