合併兩個逗號分隔字符串Clojure中

Question

我必須爲空兩逗號分隔字符串：

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

我怎樣才能在Clojure的合併字符串如下：

stringResult "aw,bx,cy,dz" 

注意：逗號分隔的值在數字上相同，均爲stringA和stringB。

Answer 1

如果逗號分隔的項目可以有多個字符：

(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"
