NettetFind median of unsorted array in O ( n) time. To find the median of an unsorted array, we can make a min-heap in O ( n log n) time for n elements, and then we can extract one by one n / 2 elements to get the median. But this approach would take O ( n log n) time. Can we do the same by some method in O ( n) time?
