You are given a binary string s.
Return the number of with dominant ones.
A string has dominant ones if the number of ones in the string is greater than or equal to the square of the number of zeros in the string.
Example 1:
Input: s = "00011"
Output: 5
Explanation:
The substrings with dominant ones are shown in the table below.
| i | j | s[i..j] | Number of Zeros | Number of Ones |
|---|---|---|---|---|
| 3 | 3 | 1 | 0 | 1 |
| 4 | 4 | 1 | 0 | 1 |
| 2 | 3 | 01 | 1 | 1 |
| 3 | 4 | 11 | 0 | 2 |
| 2 | 4 | 011 | 1 | 2 |
Example 2:
Input: s = "101101"
Output: 16
Explanation:
The substrings with non-dominant ones are shown in the table below.
Since there are 21 substrings total and 5 of them have non-dominant ones, it follows that there are 16 substrings with dominant ones.
| i | j | s[i..j] | Number of Zeros | Number of Ones |
|---|---|---|---|---|
| 1 | 1 | 0 | 1 | 0 |
| 4 | 4 | 0 | 1 | 0 |
| 1 | 4 | 0110 | 2 | 2 |
| 0 | 4 | 10110 | 2 | 3 |
| 1 | 5 | 01101 | 2 | 3 |
Constraints:
1 <= s.length <= 4 * 104s consists only of characters '0' and '1'.
