Your task is to write a program which, given a number and a string, splits the string into chunks of that size and reverses them.
Your program will receive a positive integer
n, as well as a string
s with length at least one consisting of only printable ASCII (not including whitespace). The string should then be split into chunks of length
n, if the length of the string isn't divisible by
n any leftover at the end should be considered its own chunk. Then, reverse the order of the chunks and put them together again.
n s Output 2 abcdefgh ghefcdab 3 foobarbaz bazbarfoo 3 abcdefgh ghdefabc 2 a a 1 abcdefgh hgfedcba 2 aaaaaa aaaaaa 2 baaaab abaaba 50 abcdefgh abcdefgh 6 abcdefghi ghiabcdef
This is code-golf, so you should aim for as few bytes as possible.
