Write a function that converts a sentence into pig latin.

Rules for converting to pig latin:

• For words that begin with a vowel (a, e, i, o, u), add "way".
• Otherwise, move all letters before the first vowel to the end and add "ay".
• For simplicity, no punctuation will be present in the inputs.

Examples

pig_latin_sentence("this is pig latin") ➞ "isthay isway igpay atinlay"

pig_latin_sentence("wall street journal") ➞ "allway eetstray ournaljay"

Notes

All letters will be in lowercase.
