Write the shortest possible program or function that will join a list of columnar strings.
For this challenge, columnar strings are defined as one-character-wide strings spanning across multiple lines. Each character, except for the last one, is separated by a newline character. Some examples, separated by ---:
a
b
c
d
---
h
e
l
l
o
---
c
o
d
e
g
o
l
f
---
"
q
u
o
t
e
s
"
Given a list of columnar strings, join them into a single string with multiple columns. If the columnar string is longer than its surroundings, it should be left-padded by spaces.
Notes
- This is code-golf, so shortest code wins!
- You may assume inputs are ASCII only.
- You may have trailing newlines.
- You may have trailing spaces.
- This is not a transpose challenge a transpose challenge;; each input string in the input list of strings has newlines separating each character. The "multi-line strings vs list of strings as input" default does not apply here; each string in the test cases are separated by
---and include newlines.
