合并两个逗号分隔字符串Clojure中

Question

我必须为空两逗号分隔字符串：

stringA "a,b,c,d" 
stringB "w,x,y,z" 

我怎样才能在Clojure的合并字符串如下：

stringResult "aw,bx,cy,dz" 

注意：逗号分隔的值在数字上相同，均为stringA和stringB。

Answer 1

如果逗号分隔的项目可以有多个字符：

(defn combine 
    [stringA stringB] 
    (let [seqA (clojure.string/split stringA #",") 
     seqB (clojure.string/split stringB #",") 
     combined (map str seqA seqB)] 
    (clojure.string/join "," combined))) 

Answer 2

(.replace (apply str (map str stringA stringB)) ",," ",") 
;=> "aw,bx,cy,dz"
