Input Format
First and only argument is a string A.



Output Format
Return an array of integers denoting the answer.



Example Input
Input 1:

A = "010"
Input 2:

A = "111"


Example Output
Output 1:

[1, 1]
Output 2:

[]


Example Explanation
Explanation 1:

A = "010"


Pair of [L, R] | Final string
___________|_________
[1 1] | "110"
[1 2] | "100"
[1 3] | "101"
[2 2] | "000"
[2 3] | "001"



We see that two pairs [1, 1] and [1, 3] give same number of 1s in final string. So, we return [1, 1].

Explanation 2:

No operation can give us more than three 1s in final string. So, we return empty array [].
