I had this question in my test and I couldn’t solve it.

any answer less than O(n2) time complexity is fine.

ex- array = [4,3,12] all sub-arrays = [4], [3], [12], [4,3], [3,12], [4,3,12] expected ans - [4], [4,3,12]

1 <= array length <= 2*10^5
1 <= array[i] <= 200

I was doing it in the companies platform, so I don’t have my code now but it wasn’t passing all testcases and some of them were TLE.
