Find Median Of Unsorted Array In Linear Time. Since N 5 which is odd therefore the median is the 3rd element in the sorted array. Jul 11 2020 array 5 4 3 1 2 6 If the array was sorted then it would be 1 2 3 4 5 6 and the middle element would be 3.
So to find the median of the unsorted array we need to find the middle element s when the array will be sorted. The algorithm works by dividing a list into sublists and then determines the approximate median in each of the sublists. If there are two middle numbers the median is.
These are recursive steps.
Mar 31 2020 If k is small the time complexity gets very close to linear time On. Then it takes those medians and puts them into a list and finds the median of that list. At step 2 you sort an array of size that is always 5 so its in fact O 1 for this small array ie. Since N 5 which is odd therefore the median is the 3rd element in the sorted array.
