Clojurians Log v2

hey guys, need some help the problem is quite simple:

Given two unsorted arrays team-a and team-b. They may contain duplicates. 
For each element in team-b count elements less than or equal to it in array team-a

(defn solution [team-a team-b]
    (let [steam-a  (sort team-a)
          search #(java.util.Collections/binarySearch steam-a %1)
          mapper  (comp inc search)]
       (mapv #(Math/abs (mapper %1)) team-b)))

the bottleneck here is the binarySearch, is taking around 1 ~2 millisecond per call

You might want to turn on reflection checks. It might indicate a lot of time figuring it out. Alternatively, use async-clj-profiler to pinpoint it exactly

Gonna try this @dominicm . Let you know what I found
