// Example 1 string input = "Hello World"; string output = StringHelper.AddBrace(input); // output = "{Hello World}" // Example 2 string input = "SELECT * FROM Customers WHERE CustomerId = @CustomerId"; string output = StringHelper.AddBrace(input); // output = "{SELECT * FROM Customers WHERE CustomerId = @CustomerId}"In the first example, we pass a string "Hello World" to the AddBrace method, and it returns the same string with braces added around it. In the second example, we pass a SQL query string, and it returns the same string with braces added around it. It's unclear which package or library this StringHelper belongs to, as there are many third-party libraries and frameworks that could provide such a utility method. It could be a custom utility class defined within the project, or it could be part of a third-party library that provides general string manipulation utilities.
