Create the pattern of a chess board that is 8 x 8. Use X and O to represent the squares.

Create the appropriate nested looping structure to output the characters in an 8 x 8 grid on the screen using Console.Write() or Console.WriteLine() as appropriate.
Include a decision structure to ensure that alternate rows start with opposite characters as a real chess board alternates the colors among rows.
This is what your output should look like.

{
email = read_Email.GetValue(i).ToString();
list_emails.Add(email);

Sahendrin Commercial Bank updates its customers’ accounts at the end of each month.
The bank offers two types of accounts: savings and current. Every customer must maintain a minimum balance, minimum balance for savings account is GHC 50.00 and current account is GHC 100.00. If a customer’s balance falls below the minimum balance, there is a service charge of GHC 10.00 for savings accounts and GHC 25.00 for current accounts.
If the balance at the end of the month is at least the minimum balance, the account receives interest as follows:
• Savings accounts receive 4% interest.
• Current accounts receive 5% interest.
Write a program that reads a customer’s account number (int type), account type, current balance. The program should then output the account number, account type, current balance, and an appropriate message.

Three friends set out to explore a remote area. They choose a safe place and make it their Base Camp. To speed up exploration time they decide to work independently. At any given point, either one or more of them can set out to explore the area. They set a protocol that after exploring the area they must meet back at the Base Camp in the evening and exchange notes.

The remote area consists of accessible and inaccessible pieces of land. Being ordinary humans, they must walk only the accessible piece of land. In order to maximize their exploration time, each one is interested in knowing about a shortest path back to the base camp.

Given that the area under exploration is arranged in form of a rectangular grid, help the explorers to chalk out a shortest path back to the base camp. Properties of a rectangle can be used as heuristic in computing distance between their positions and the Base Camp. Your task is to find out and mark the shortest path for each explorer and print each path as a separate grid.
