What I essentially want to do is keep folding an array from left to right with an operator, and then stopping what I hit a total so some number X.
I expect the results to be 10, or true. Basically anything that lets me know that somewhere in my fold I found the number 10.
Is there anything function currently in Julia that operates like this?
Sounds like your best option might just be a for loop. You could make
foldl_special that does this with one pretty easily.
Yeah I can manage it on my own, I was just curious if anything had the functionality already built in.
Not as far as I’m aware. I might be wrong though.
You can do
julia> foldl(right, Scan(+) |> ReduceIf(>=(10)), [1, 2, 2, 6, 7])
julia> foldl(right, Map(x -> @show x) |> Scan(+) |> Map(sum -> @show sum) |> ReduceIf(>=(10)), [1, 2, 2, 6, 7])
x = 1
sum = 1
x = 2
sum = 3
x = 2
sum = 5
x = 6
sum = 11
