An answer on Brainly can only be marked as Brainliest if the individual who answered the question is not yourself, and if one week has passed since the answer was posted. Once the week has passed and the answer is still there (has not been removed) then a Brainliest button should appear that will allow you to mark the answer as Brainliest. Simply click the button and the answer will be marked as Brainliest.
The time complexity can only shift to 3 with the last instance. For the 2nd case, they need one parallel. However, 2 parallels are needed to sort with splitting into 3-way frames.
It decreases the number of passes even after breaking the collection in 3 by increasing contrast. So, the time complexity remains the same but the log is divided into 3 bits.
