Find the First Out-of-Order Spot

The domino artist lined up numbered dominoes and something's off — find the first spot where the order breaks. 🁢

You get the nums. Print the position (from 0) of the first number that is BIGGER than its next neighbor, or sorted if the line never breaks.

Example:

Input: nums = [1, 5, 3, 7] Output: 1

5 > 3 at position 1 — that's the first spot where the order breaks.
