Alternating-Split

Simple Encryption #1

For building the encrypted string: Take every 2nd char from the string, then the other chars, that are not every 2nd char, and concat them as new String. Do this n times!

Examples:

"This is a test!", 1 -> "hsi etTi sats!" "This is a test!", 2 -> "hsi etTi sats!" -> "s eT ashi tist!" Write two methods:

String encrypt(final String text, final int n) String decrypt(final String encryptedText, final int n) For both methods: If the input-string is null or empty return exactly this value! If n is <= 0 then return the input text.
