是否可以在q脚本中编写k代码？

Question

我尝试从q函数调用k的count函数，但是它给出了错误。

{
  "k)"# 1 2 3 4 5 //~ count 1 2 3 4 5
 }[]

因此，我有以下问题：
1.是否可以在q脚本中编写k代码？
2.如果是，那么我们如何在q脚本中编写k个代码？在q脚本/函数中使用k代码是否会使脚本/函数更高效和更优化？

Answer 1

1. Yes it is possible. I think what you are looking for is

{
 (#:) 1 2 3 4 5
}[]

This will perform a count on the list

2. In terms of speed, for functions like count the effect seems to be negligible.

q)\t:100000 {(#:) 1 2 3 4 5}[]
29

q)\t:100000 {count 1 2 3 4 5}[]
25

Hope this answers your question
