The floor function of any real number a is the integer number denoted by \lfloor a\rfloor such that \lfloor a\rfloor \leq a and \lfloor a\rfloor>a-1. For example, \lfloor 5\rfloor=5,\lfloor\pi\rfloor=3 and \lfloor-1.5\rfloor=-2.
Find the difference between the largest integer solution of the equation \lfloor x / 3\rfloor=102 and the smallest integer solution of the equation \lfloor x / 3\rfloor=-102.
