    A
   B B
  C   C
 D     D
E       E
 D     D
  C   C
   B B
    A

Input

Output

The output should be (2*N - 1) rows and (2*N - 1) columns containing the alphabet characters in the hollow diamond pattern.

Explanation

For example, if the given number is 5, the pattern should contain 9 rows and 9 columns as shown below.

    A
   B B
  C   C
 D     D
E       E
 D     D
  C   C

It should pass:

When the HTML button element with attribute type submit is clicked,if the values of the HTML input elements with ids name and password are not empty then text content in the HTML paragraph element with id resultMsg should be displayed as "Login Success".

When the HTML btn element with attribute type submit is clicked,if the values of the HTML input elements with ids name and password are empty then text content in the HTML paragraph element with id resultMsg should be displayed as "Fill in the required details".

When the submit is clicked and the value of the HTML input elements with id name is empty and password is not empty then the text content in the HTML paragraph element with id nameErrMsg and resultMsg should have an error message and "Fill in the required details" respectively.

1.Make a Console App with a class that encapsulates the following information about a bird: English name, Latin name, and Date last seen. Allows the user to fill in the details about a bird. The data is saved in a Bird object, which is then displayed to the user. 2.In the program, create a superclass called Animal and update class Bird to inherit from it. Create a new class named Butterfly that allows the user to collect butterfly data. 3.Display the percentage of birds and butterflies in the app when displaying the birds and butterflies. When there are no entries in the app yet, use exception handling to handle the divide by zero. 4.Create an interface called ISighting with a single method called displaySighting. Implement the interface in Animal but leave the displaySighting method abstract. Implement the displaySighting method in both the Bird & Butterfly classes to display all the information known about the animal to the console.Update app so that the user can choose to add a bird or a butterfly.

Riya took part in a maths quiz competition. To win the prize money she has to solve a tricky question at the end.For a given list of integers, write a program where all the integers in a given index range to be added.

She will be given M multiple ranges, where she should print the sum of numbers for each corresponding range.

Note: The limits in the range are both inclusive.

Input

The first line f input is space-separated integers.

The second line of input is a positive integer M denoting the number of index ranges.

The next M lines contain two space-separated integers of the range.

Output

The output should be M lines.

Each line contains an integer that represents the sum for the corresponding ranges.
