Hi Pranjal
Make sure that you are defining array in string data type and taking M inputs in char and then using an another put one by one values from that string using charAt().
try to implement this logic and let me know if you still face any issue.

Hi Pranjal
Hope this will help you:-

 Scanner s=new Scanner(System.in);
    
        int m=s.nextInt();
        int n=s.nextInt();

        String[][] maze=new String[m][n];
        int[][] v=new int[m][n];
        int[][] sol=new int[m][n];
        for(int i=0;i<m;i++)
        {

            String str=s.next();
            for(int k=0;k<str.length();k++) {
                char cc=str.charAt(k);
                if(cc=='X') {
                    v[i][k]=1;
                }
            }          

       }
    m--;
    n--;
