(1)Upper bound of S_{1 }= { 3 , 4 , 5 , 6 , 7 , 8 }
Lower bound of S_{1 }=not Exists
Upper bound of S_{2 }= { 6 , 7 , 8 }
Lower bound of S_{2 }= { 1, 2, 3 }
(2)GLB(S_{1})=not Exists
LUB(S_{1})=not Exists
GLB(S_{2})= 3
LUB(S_{2})=not Exists
make arrow in image
for LUB = go for upward direction from that set and take 1st meeting point .
for GLB = go for lower direction from that set and take 1st meeting point .
@Anirudh. Plz guide me.
LUB(S_{1})=3 I think because this is the first meeting pt of 1 and 2, right?
LUB(S_{2})=6 I think because 3,4,5 meet here for the first time, right?
