[hackerrank][java8][clojure] SolveMeFirst

int 두개 더하기
java

static int solveMeFirst(int a, int b) {
  return a + b;     
}

clojure

(defn solveMeFirst [x y]    
    (+ x y))

여기서 특이한 점은 stdin, stdout 방법을적어놔야할 것 같다. 자바

Scanner in = new Scanner(System.in);
int a = in.nextInt();
int b = in.nextInt();
int sum = solveMeFirst(a, b);
System.out.println(sum);

클로저

(def a (read-line))
(def b (read-line))

(println (solveMeFirst (Integer/parseInt a) (Integer/parseInt b)))
