Recent solutions I'm happy with (just starting/trying this):

Dang it no markdown here?

First one is my simplification of agave’s, see [here](https://leetcode.com/problems/ugly-number-ii/discuss/69397/Sharing-very-simple-and-elegant-Python-solution-using-heap-with-explanation/71469).

This is BS-StefanPochmann
Binary search. Takes almost no memory at all. Solved n=10^6 in 0.35 seconds and n=10^9 in 15 minutes on a 2.25 GHz CPU.

n=10^9 in 2 minutes-StefanPochmann
Solved n=10^6 in 0.07 seconds and n=10^9 in 120 seconds on a 2.25 GHz CPU (using 493 MB memory for 10^9).
The following version is my fastest, solved n=10^9 in 114 seconds, but it's more complicated and I don't like it much. It simulates the main deque with two lists.
```

Saw veky's title and tags, no idea how he's using `getattr`.

del a[-1:]-StefanPochmann

Checked all solutions, didn't see anybody doing this. Even though quite a few people used the inefficient `a = a[:-1]`. Weird.

Very nice, and you inspired me to write a [min version](http://www.checkio.org/mission/gcd/publications/StefanPochmann/python-3/min-/) :-)

We should have a "Tardy" category for highly inefficient solutions like this :-P
