title: Find the median of an unsorted array without sorting
body: <p>is there a way to find the Median of an unsorted array:
  1- without sorting it.
  2- without using the select algorithm, nor the median of medians</p>
  
  <p>I found a lot of other questions similar to mine. But the solutions, most of them, if not all of them, discussed the SelectProblem and the MedianOfMedians</p>
