public class Solution extends Object
1758 - Minimum Changes To Make Alternating Binary String\. Easy You are given a string `s` consisting only of the characters `'0'` and `'1'`. In one operation, you can change any `'0'` to `'1'` or vice versa. The string is called alternating if no two adjacent characters are equal. For example, the string `"010"` is alternating, while the string `"0100"` is not. Return _the **minimum** number of operations needed to make_ `s` _alternating_. **Example 1:** **Input:** s = "0100" **Output:** 1 **Explanation:** If you change the last character to '1', s will be "0101", which is alternating. **Example 2:** **Input:** s = "10" **Output:** 0 **Explanation:** s is already alternating. **Example 3:** **Input:** s = "1111" **Output:** 2 **Explanation:** You need two operations to reach "0101" or "1010". **Constraints:** * 1 <= s.length <= 104 * `s[i]` is either `'0'` or `'1'`.
