数大了，解这道题很慢。

my OPT: A -> B -> C -> D -> E

fish[1] = 3121
fish[2] = 2496
fish[3] = 1996
fish[4] = 1596
fish[5] = 1276

A: 1 -> 5
CHECK = 3121

B: 5 -> 1
CHECK = 1276

C: 5 -> 1
take = (fish-1)/5    (fish = take * 5 + 1)
CHECK = 255    (1276/5)

D: 5 -> 1
+take
jump  = 4   (take += jump)
CHECK = 64    (255/4)

E: 5 -> 1
+take
JUMP = 4**4    (take += JUMP)
lev-1 jump = 4**1
lev-2 jump = 4**2
lev-3 jump = 4**3
lev-4 JUMP = 4**4

CHECK = 0
