I try use Data.Array
code
It’s ok, but slow.
Then use Data.Array.Diff
code
Could not find module `Data.Array.Diff’
If I use Data.Array.Unboxed, than not found DiffArray or DiffUArray constructor.
How I can use DiffArray and DiffUArray?
DiffUArray more performance optimized, than DiffArray?
How I can make code less laziness (more strict)?
I don’t want use IOArray or STArray, because learning. I should use only IArray and some other not monadic arrays, if it exist.
How about using vector?
DiffArray is obsolete.
