Syntax

Parameters − ‘p1’ is the predicate which needs to be tested. ‘col’ is the collection of values which needs to be tested.

Return Value − Returns true if the predicate is true for every value, else false.

Example

Following is an example of some in Clojure.

   (:gen-class))
(defn Example []
   (println (some even? '(1 2 3 4))))
