Clojure-如何在向量中添加连续对? [英] Clojure-How to add successive pairs in vector?

问题描述

尝试编写一个递归函数，将连续对添加到向量中.

Trying to write a recursive function that adds successive pairs in a vector.

[1 2 3 4] => [3 5 7]

几乎卡住了，这就是我目前所拥有的:

Pretty much stuck and this is what I have currently:

(def tmp  [ 1 2 3 4])

user> (map #(+ (second %) (first %)) (partition-all 2 tmp ))

这是错误的，因为它只添加了对而不是连续的对.我得到 [3 7] 而不是 [3 5 7]

This is wrong as it adds just the pairs and not successive pairs. I get[3 7] instead of [3 5 7]

推荐答案

这是另一种可能的解决方案:

Here is another possible solution:

(def tmp [1 2 3 4])

(map + tmp (rest tmp))
