For this Question: You are given a binary string s. You are allowed to perform two types of operations on the string in any sequence:

Type-1: Remove the character at the start of the string s and append it to the end of the string.
Type-2: Pick any character in s and flip its value, i. e., if its value is '0' it becomes '1' and vice- versa.
Return the minimum number of type-2 operations you need to perform such that s becomes alternating.

The string is called alternating if no two adjacent characters are equal.

For example, the strings "010" and "1010" are alternating, while the string "0100" is not.There is a binary string s is given as input.

<b>Constraints</b>
1 <= s.length <= 10<sup>5</sup>
s[i] is either '0' or '1'.Return the minimum number of type-2 operations you need to perform such that s becomes alternating.Sample Input:
111000

Sample Output:
2

Explanation: Use the first operation two times to make s = "100011".
Then, use the second operation on the third and sixth elements to make s = "101010"., I have written this Solution Code: import java.util.HashSet;
import java.util.*;

public class Main
{
    public static int minFlips(String s) {
          int n=s.length(); 
    s=s+s;
    char t[]=s.toCharArray();
    char  a[]=new char[n+n];
    char b[]=new char[n+n];
    for(int i=0;i<n+n;i++)
    {
        if(i%2==0)
        {
            a[i]='1';
            b[i]='0';
        }
        else
        {
            a[i]='0';
            b[i]='1';
        }
    }
    int f=0,sec=0,ans=Integer.MAX_VALUE;
    for(int i=0;i<n+n;i++)
    {
        if(a[i]!=t[i])
            f++;
        if(b[i]!=t[i])
            sec++;
        if(i>=n)
        {
            if(a[i-n]!=t[i-n])
                f--;
            if(b[i-n]!=t[i-n])
                sec--;
        }
        if(i>=n-1)
            ans=Math.min(ans,Math.min(f,sec));
            
    }
    return ans;
    }
    public static void main(String[] args)
    {
        Scanner sc=new Scanner(System.in);
        String s=sc.next();
		int ans=minFlips(s);
		System.out.println(ans);
    }
}

, In this Programming Language: Java, Now tell me if this Code is compilable or not?
