In Oracle, a calculated field such as item_price * item_quantity differs from a tablefield in what way?1)A calculated field should be saved in the table after its value has beencomputed.2) A sum cannot be computed for a calculated field.3) There is no difference. They are just synonyms for the same concept.4)A calculated field's value appears in the output of a SELECT statement, but itis not physically stored as a field in the table.

Option 4: 4) A calculated field's value appears in the output of SELECT statement, but it not…

Answered: O 4) A calculated field's value appears…

O 4) A calculated field's value appears in the output of a SELECT statement, but it is not physically stored as a field in the table.

Data structures unique_values(a_dict:dict)-> dict This function will receive a single dictionary parameter known as a_dict. a_dict will contain a single letter as a string and numbers as values. This function is supposed to search a_dict to find all values that appear only once in the a_dict. The function will create another dictionary named to_ret. For all values that appear once in a_dict the function will add the value as a key in to_ret and set the value of the key to the key of the value in a_dict (swap the key-value pairs, since a_dict contains letters to numbers, to_ret will contain Numbers to Letters). Finally, the function should return to_ret. Example: a_dict: {'X': 2, 'Y': 5, 'N': 2, 'L': 2, 'W': 1, 'G': 0, 'R': 1} Expected: {5: 'Y', 0: 'G'} a_dict: {'Z': 3, 'P': 3, 'E': 2, 'G': 0, 'T': 5, 'L': 1, 'Q': 0} to_ret: {2: 'E', 5: 'T', 1: 'L'} a_dict: {'E': 3, 'X': 3} to_ret: {} a_dict: {'G': 3, 'D': 3, 'C': 4, 'Q': 1, 'H': 1, 'M': 2, 'Z': 1, 'W': 3} to_ret: {4: 'C', 2: 'M'}…

discrete structure could you help me with these two questions
True or False Before you can use the structure to store data, you must create an instance of the structure in memory.

C# program in Visual Studio Code. I need to be able to enter five integer values and then have the Unique values entered display. Private member variable to store 5 unique values (hint: use an Array or a List) Public function to get 5 unique values from the user and store them in the member variable loop to get the numbers, if a number is already stored, ignore it and keep looping until you have 5 unique numbers if a number is out of range, don't store the value, throw an exception and handle it in such a way that you don't break the loop but do message the user that the value was out of range

assign(self, assignment:Assignment) -> AssignmentResult: """ This function is to simulate the process of the student receiving an assignment, then working on the assignment, then submitting the assignment and finally receiving grade for the assignment. This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later. Then an Assignment Result object should be created with the student's ID, the assignment…
