Perl 5, 47 bytes
45 bytes plus two for the
-lF flags (
-M5.01 is free):
perl -lF -M5.01 script.pl
-lFreads the input, removes the trailing newline, splits up the remainder into characters, and puts that split into the array
#s in the input string and sets
$`equal to the stuff before it and
$'equal to the stuff after it.
"$'$`"is thus the number of times to rotate the array.
- Now comes a loop: We increment
$i(which starts at
0) and test against
"$'$`"(the number of times to rotate); if we haven't reached
redothe loop. What does the loop do? Simple: it rotates the array (
pops the last element and
unshifts it onto the beginning).
- After the loop exits, we print all the elements of the rotated array.
