Did anyone come up with a nice Jish solution for this?
Mine (see below) ended up being very scalar.
countJumps=: 3 :0
count=. idx=. 0
offsets=. y
while. (0 <: idx) *. (idx < #offsets) do.
count=. count + 1
idx_new=. idx ([ + {) offsets
offsets=. idx (1 + {)`[`]} offsets
idx=. idx_new
end.
count;idx;offsets
)
countJumps 0 3 0 1 _3
