Implement a bool function whose header is given below. Inside the function, declare, ask, and get a character from the user. The function will return true if the character the user enters is NOT in either of the words, otherwise it will return false. Keep in mind that uppercase and lowercase letters are not the same. You will need to change both words and the character input by the user to the same case (upper or lower) -...

System.out.println("infix expression is");
et.inorder(root);
return et;
}
In the above method, et needs to have a value.
