Decipher this!

DESCRIPTION:

You are given a secret message you need to decipher. Here are the things you need to know to decipher it:

For each word:

• the second and the last letter is switched (e.g. Hello becomes Holle)
• the first letter is replaced by its character code (e.g. H becomes 72)

Note: there are no special characters used, only letters and spaces

Examples

decipherThis('72olle 103doo 100ya'); // 'Hello good day'
decipherThis('82yade 115te 103o'); // 'Ready set go'
