//
//  Given sets
//		set_a = {2, 9, 6, 4}    set_b = {3, 6, 2, 8, 7}
//

  a) set_a + seb_b = { 2, 3, 4, 6, 7, 8, 9 }	// a | b		bitwise OR		union
  
  
  b) set_a * set_b = { 2, 6 }					// a & b		bitwise AND		intersection
  
  
  c) set_a - set_b = { 9, 4 }					// a & (b ^ 255)				difference
  
  
  d) set_b - set_a = { 3, 7, 8 }
