Function g and f7 each contain tie. I can't understand where and how
it is used in f7. The tree looks just like h rather than g. Where is tie
used in f7?
g=:<`(1,1:)
5!:4 <'g'
-- (<,'<'),<(<,'3'),<(<(,'0');1),(<,','),<'1:'
h=:<(1,1:)
5!:4 <'h'
-- <
--+ -- 1
L---+- ,
L- 1:
f7=:[:,([:+/\|.)^:2^:(<`(1,1:))
5!:4 <'f7'
-- [:
+- ,
│ -- [:
--+ ----+- \ --- / --- +
│ -- ^: -+ L- |.
│ │ L- 2
L- ^: -+
│ -- <
L------+ -- 1
L---+- ,
L- 1:
f7 6
1 1 2 3 5 8 13 21 34 55 89 144
