Recur Example with Head and Tail in Clojure Programming [quads id=8] Hi! Here I shows you a Simple Recur Example in Clojure Programming Language. And the recur Function in Clojure is an easy Looping Tool. It simply repeat the Execution of Function from where is triggered. Moreover, it redefine the Paramenters given to the Function at each Call. Finally, a frequent use of recur is in an Head & Tail Recursion. Example of recur So here is a symbolic recur Example With a Head & Tail Looping: (defn loop-head-tail [Items Result] … (if (CONDITION) Result (recur (rest Items) (DOSOMETHINGWITH (first …
Clojure Array of Maps Extract Keyword Values
Array of Maps Get Keyword Values in Clojure [quads id=8] Hi! Here I shows you How to Extract Keyword Values in Array of Maps in Clojure Programming Language. And to easily achieve this outcome I simply make use of the map Functions. Especially relevant: we can easily getting this Result because in Clojure you can use Keywords as Functions. Get Keyword Values in Array of Maps So, for instance, if we have a most populated Cities Array of Maps like: (def cities [ {:name “Tokyo” :pop 37.5} {:name “Delhi” :pop 28.5} {:name “Shangai” :pop 25.5} {:name “Sao Paulo” :pop 21.5} …
Clojure Sum Keyword Values in Array of Maps
Sum Keyword Values in Array of Maps Clojure [quads id=8] Hi! Here I shows you How to Sum Keyword Values in Array of Maps in Clojure Programming Language. And to easily achieve this outcome I make use of the reduce and map Functions. Especially relevant: we can easily getting this Result because in Clojure you can use Keywords as Functions. Sum Keyword Values in Array of Maps So, for instance, if we have a most populated Cities Array of Maps like: (def cities [ {:name “Tokyo” :pop 37.5} {:name “Delhi” :pop 28.5} {:name “Shangai” :pop 25.5} {:name “Sao Paulo” :pop …
Clojure Reduce Syntax
Reduce Syntax Clojure [quads id=8] Hi! Here I shows you the Reduce Function Syntax in Clojure Programming Language. And what I intend to Highlight here is simply the fact of an Initial Value to Set optionally. Like map, reduce takes a Function and a Sequence and calls the Function for each Item in the Sequence. Unlike map, reduce can take an Initial Value, and instead of acting on the Elements of the Set, produce a Final Result. Each time reduce calls your Function, it Updates the Current Result with the Return Value from that call. When reduce runs out of …
Clojure Loop Head & Tail Split and Recursion on Tail
[quads id=4] Said we have a Loop like this: (loop [remaining-parts STARTINGPARTS RESULT [RESULTSTARTINGVALUE+TYPE]] (if (IFCLAUSE) FINALRESULTOUTPUT (let [[head & tail] remaining-parts] ;; Splitting in Head & Tail (recur tail (DOSOMETHINGWITH head …))) ) ) First, we Split in “head & tail” the recursive Value using the “let” Function: (let [[head & tail] remaining-parts] ;; Splitting in Head & Tail Then with : recur tail The “tail” straight become the recursive Value and so in this case the “remaining-parts”
Clojure Loop Multiple Return Values
Clojure Loop Multiple Return Results [quads id=8] Hi! Here I shows you How to Return Multiple Values from a Loop in Clojure Language. And to achieve a Multi Result return you have simply to enclose them into a Vector. Clojure Multiple Return from Loop So here is the simple General Form First, of course them has to be declared on the Loop like: loop [iterator x first-item [FIRST-STARTVALUE] second-item [SECOND-STARTVALUE] …] To put them into a Vector like for instance: [first-item second-item]
