其實我主要想問唔係呢樣.
我係想講出... a貨弊換b貨弊..假若a貨弊比b貨弊weak..咁就換得少b貨弊
但如果兜一個圈...a貨弊換左c 貨弊先 而c貨弊比b貨弊又超強..
咁樣再用c貨弊去得到b貨弊..
比起dire ...
Let a = 4 , b= 2 , c =8
/\<------C
/ \
/ \
A---->/ \
\
\<--------B
__________/ /_________

A B
final
A not same to b, inverse your case
B want to get A ,Sure the cost must less than A
