You could use (-1)^{i+1}, which would be a bit more mathy but it may not be efficient. (defn altsum [n] (->> (range 1 (inc n)) (map #(* % (Math/pow -1 (inc % (reduce +))) On Nov 13, 2014, at 6:31 PM, Andy L wrote: > Hi, > > All I was able to come up with was this > > (de

Re: better way to group consecutive numbers in a vector?

I think what you want is `partition-between` as implemented by amalloys useful lib (https://github.com/amalloy/useful/blob/develop/src/flatland/useful/seq.clj#L224 ). `(partition-between (fn [x y]

have two assertions. In this scenario, your test suite will actually run faster in a standard, serial test run, than in the parallel (by namespace) test run. Feel free to benchmark your testing tool against Pedestal's test suite - it's a good mix of different size testing namespace

Re: Schrodinger's cat in clojure?

Transducers build up transformation steps, with new generic operations like single arg `map` and `filter`, and then apply these transformations to a collection using an evaluation function. This function decides if operations are done lazily, eagerly, or on a channel. Note that while this makes
