for (x-y)/-z to be the smallest...

x-y should be small and z as big as possible...

let x =19 and y = 1
(19 -1) / -1 = -19
since the numbers have to be distinct

make either y =2 or z =2 and see which is the smallest

y =2 and z = 1

(19-2) / -1 = -17
or
z = 2 and y = 1
(19 -1) / -2 = -9

since -17 is lesser...
choose B
