13. Remove Duplicates from Sorted Array
Given an array nums sorted in non-decreasing order, remove duplicates in place so each element appears once, and return the new length.
Example 1:
Input: nums = [1,1,2] Output: 2
Example 2:
Input: nums = [0,0,1,1,1,2,2,3,3,4] Output: 5
Constraints:
1 <= nums.length <= 3 * 10^4nums is sorted in non-decreasing order.
