In this video, I solve LeetCode 66: Plus One using an optimized and in-place JavaScript solution.

Given an array of digits representing a non-negative integer, the goal is to add 1 to the number and return the resulting digits as a new array.

This solution handles:
✅ Regular digit addition
✅ Carryover from 9 to 0
✅ Full array carryover like [9,9,9] → [1,0,0,0]

Time Complexity: O(n) – where n = digits.length
Space Complexity: O(1) – modifies array in place (not counting output)
