class Reverse {
    // Method to reverse a given string
    public static String reverseWord(String str) {
        // Get the length of the input string
        int len = str.length();

        // Create a StringBuilder to construct the reversed string
        StringBuilder reversed = new StringBuilder();

        // Traverse the input string from end to start
        for (int i = len - 1; i >= 0; i--) {
            // Append each character to the StringBuilder in reverse order
            reversed.append(str.charAt(i));
        }

        // Convert the StringBuilder to a string
        String reversedString = reversed.toString();

        // Return the reversed string
        return reversedString;
    }
}
