Weave Strings Together

+3

−0

Given a list of strings(and optionally, their length) as input, weave the strings together.

Intro

Your goal is to mimic the WV operator in Pip. Take a list of strings and alternate between their characters like so:

hello,
world, → hwc,eoo,lrd,lle,od → hwceoolrdlleod
code

Effectively, you need to group the characters at each index, and join them into a single string.

The strings may have spaces.

No truncation should be done, and all the characters of each string must be used.

Test Cases

Without the outputs

["kino","cinema","movie"] → kcmiionnvoeimea
["code","golf"] → cgoodlef
["Hi","","There"] → HTihere
["Explanation"] → Explanation
["Dyalog APL","Cultivation","Orchard"] → DCOyuralclthoiagvr adAtPiLon

You check any other test cases with this program.

Ugh, the "strings may have spaces" and the way you don't pad the strings makes it unusually annoying. — Quintec‭ 2 months ago

Can we take the strings as an array of characters? — Shaggy‭ 2 months ago

@Shaggy yes, you can — Razetime‭ 2 months ago

Õc with the -P flag would work, taking the strings as character arrays. — Shaggy‭ 2 months ago

Full program. Prompts for list of strings from stdin.

0~⍨,⍉↑0,¨⎕

Try it online!

⎕ prompt for list of strings

0,¨ prepend a zero to each

↑ convert to orthogonal matrix (increase rank at cost of depth), padding with 0s

⍉ transpose

, ravel (flatten)

0~⍨ remove 0s
