In this guide, we will discuss Clojure map-invert. Inverts the maps so that the values become the keys and vice versa.

Syntax

Following is the syntax.

(map-invert hmap)

Parameters − ‘hmap’ is the map of hash keys and values.

Return Value − Returns a map with the values inverted to the keys and the keys inverted to values.

Example

Following is an example of map-invert in Clojure.

(ns clojure.examples.example
   (:require [clojure.set :as set])
   (:gen-class))
(defn example []
   (def demokeys (hash-map "z" 1 "b" 2 "a" 3))
   (def demonew (set/map-invert demokeys))
   (println demonew))
(example)

Output

The above code produces the following output.
