Based on the code you've given:
nums.sort(): Is O(nlogn) where n = size of original array. Because array is already sorted then you don't need to sort again anyway.
nums.sort()
You can also use a Map to keep track of already seen items.
The example shows integers but the problem statement does not mention any restrictions on the types. Will this work on any type?
