Remove duplicate from sorted array ...
Approach
Optimized Approach (Two Pointers)
💡 Idea
Because the array is sorted, duplicates are always next to each other.
We maintain:
i → slow pointer (position of last unique element)
j → fast pointer (to scan array)
Whenever we find a new unique element, we move i forward and copy that element.
🧠Algorithm Steps
If array length is 0 → return 0
Initialize i = 0
Loop j from 1 to n-1:
If nums[j] != nums[i]
Increment i
nums[i] = nums[j]
Return i + 1 (count of unique elements)
