Append and Delete

    Hi I tried with no more than a simple if else and I could, just my logic is kind of weird but works.

    public static String appendAndDelete(String s, String t, int k) {
    // Write your code here
        
        int uno = s.length();
        int dos = t.length();
        
        if (s.equals(t))
        {return "Yes";}
        else if (s.length()>t.length() & (uno -dos) > k ){
            
            return "No";
        }else if (s.length()<t.length() & (dos-uno) == k/2 & s.charAt(uno-1) == t.charAt(dos-1)){
            
            return "Yes";
        }
        else if (s.length()<t.length() & (dos-uno) < k){
            
            return "No";
        }
        else if (s.length()== t.length() & (uno/2) > k/2 ){
            
            return "No";
        }else if (s.charAt(0)!= t.charAt(0) && s.length()>k/2){
            return "No";
        }
        
        return "Yes";

    }

}
