Question

花园里5立方米的木材如何处理？

Answer 1

您可以使用

reduce

来组合数组：

WITH path,
     extract(n IN nodes(path)| n.name) as names,
     extract(r IN relationships(path)| r.metric) as metrics
RETURN HEAD(names) + 
       REDUCE(acc = [], i in RANGE(1,size(metrics)) | 
              acc  + metrics[i-1] + names[i])
