Write a program or function that takes in a string
s and integer
n as parameters. Your program should print (or return) the string when transformed as follows:
Starting in the top-left and moving down and to the right, write
s as a wave of height
n. Then, from top to bottom, combine each row as a string (without spaces).
Given the string "WATERMELON" and a height of 3:
The wave should look like this:
W R O A E M L N T E
Then, combine the rows from top to bottom:
WRO AEMLN TE
So, your program should return the string "WROAEMLNTE"
Likewise, "WATERMELON" with height 4 should produce the following wave:
W E A M L T R O E N
Your program should then return the string "WEAMLTROEN"
Input can be taken in any reasonable format. The string can be in any case you prefer. You may assume that
0 < n <= s.length
Output should consist only of the transformed string (whether returned or printed to STDOUT), plus any trailing newlines.
This is code-golf, so shortest answer in bytes wins! Standard loopholes are not allowed.
