I find this solution to be easy:

Sort(A)
candidate = 1
for i from 1 to length(A):
   if A[i] > candidate: return candidate
   else: candidate = candidate + A[i]
return candidate

First solution is crazy. 🔢 will look into it and let u know.

I can also understand this. The challenge is to do it in less than O(n lgn). O(n) solution needed
