Statement
You are given an integer array nums that is already sorted in non-decreasing order. Your task is to remove the duplicate values in-place so that each element in the array appears only once, while preserving the original relative order of the elements.
After removing the duplicates, let k be the number of unique elements remaining in the array. The first k ...
