GREATIGBOMAN:
Simple stuffz


Remember my days at leetcode.


I just add identical values in the arrays to a new array

Later check the length of each array then form a new array depending on which is longer

That's an interesting way to look at it, looking forward to your solution.

My solution:

def sort_by_frequency(arr):
   fmap = {}
   for num in arr:
     fmap[num] = fmap.get(num, 0) + 1
   arr = [ (v,k) for k,v in fmap.items() ]
   arr.sort(reverse=True)
   return [ b for a,b in arr ]

Let's see yours.

Apparently a senior software developer could not solve this coding interview problem, can you?

Given an array of numbers, list them in the order of most repeated. I.e:
[1,2,6,2,3,7,7,5,7,6,2,7] => [7,2,6,5,3,1]
