Couch 2048: How much more till 2048?

I have just tried a game called Couch 2048.
(Note: You should have a look to better understand this question.)
Since it wasn't very exciting for me, I've been asking myself 'How much more till 2048!?'
That inspired me to post a challenge, because calculating this in not as easy as I thought.
Your goal:
Given a list of balls on the sofa, you have to output how many balls with a value of 2 have to fall from the sky so that one can win the game (by reaching the 2048 ball).
- Assume the input is valid.
- Assume the player won't drop any balls.
- Assume the balls which fall from the sky always have a value of 2, as I've said.
- Valid output examples: 3, "4", [5], ["6"]
Edit:
I should clarify something:
- You have to print the smallest amount of 2s needed.
Test cases:[2048] -> 0
You've already won[1024,1024] -> 0
You don't need any more balls to win[1024,512,256,128,64,32,16,8,4,2] -> 1
One ball required to 'activate the chain'[512] -> 768
[512,2] -> 767
[4,16,64] -> 982
Notes:
I'm not a native speaker - Tell me if you spotted a typo or some non-grammatical text.
If something's unclear, ask in comments.

Welcome to PPCG. It looks like this challenge is: add all the elements in the array, subtract from2048
and divide by2
- if so, you might want to double check the last test case - if not, please use it as an example to explain why the output isn't982
.

perl -aE, 27 bytes
$"=$:;say eval"(2048-@F)/2"
This reads a line with numbers (whitespace separated) from STDIN
, and writes the answer to STDOUT
.
What it does is subtract all the numbers from the input from 2048, and it divides the remainder by 2. The -a
switch puts the in the array @F
(one number per element). If we interpolate an array into a string (which is what we are doing here), perl puts the value of $"
between the elements. The little used variable $:
is be default n-
; and since white space between tokens is ignored, the result is subtracting all the numbers from 2048. The eval
does the calculation.

perl -aE, 27 bytes
$"=$:;say eval"(2048-@F)/2"
This reads a line with numbers (whitespace separated) from STDIN
, and writes the answer to STDOUT
.
What it does is subtract all the numbers from the input from 2048, and it divides the remainder by 2. The -a
switch puts the in the array @F
(one number per element). If we interpolate an array into a string (which is what we are doing here), perl puts the value of $"
between the elements. The little used variable $:
is be default n-
; and since white space between tokens is ignored, the result is subtracting all the numbers from 2048. The eval
does the calculation.

Welcome to PPCG. It looks like this challenge is: add all the elements in the array, subtract from
2048
and divide by2
- if so, you might want to double check the last test case - if not, please use it as an example to explain why the output isn't982
