2380 - Time Needed to Rearrange a Binary String\.
Medium
You are given a binary string `s`. In one second, **all** occurrences of `"01"` are **simultaneously** replaced with `"10"`. This process **repeats** until no occurrences of `"01"` exist.
Return _the number of seconds needed to complete this process._
**Example 1:**
**Input:** s = "0110101"
**Output:** 4
**Explanation:**
After one second, s becomes "1011010".
After another second, s becomes "1101100".
After the third second, s becomes "1110100".
After the fourth second, s becomes "1111000".
No occurrence of "01" exists any longer, and the process needed 4 seconds to complete, so we return 4.
**Example 2:**
**Input:** s = "11100"
**Output:** 0
**Explanation:** No occurrence of "01" exists in s, and the processes needed 0 seconds to complete, so we return 0.
**Constraints:**
* `1 <= s.length <= 1000`
* `s[i]` is either `'0'` or `'1'`.
