A list of projects and a list of dependencies, or a list of project pairings where the second project depends on the first project, are provided to you. Before starting a project, all of its dependencies must be built. Find a build order that enables the construction of the projects. Return an error if there is no valid build order. EXAMPLEInput:projects: a, b, c, d, e, fdependencies: (a, d), (f, b), (b, d), (f, a), (d, c)Output: f, e, a, b, d, c

Create an Azure Functions project, containing a single function. The purpose of the function is to calculate the status of a module: fail, pass condoned, pass or pass with distinction. The requirements of the function are as follows:  The function must make use of an HTTP trigger.  The name of the function should be CalculateModuleStatus.  The function should accept a single MarkEntry object as input, from either a get or a post operation. Here is the definition of the MarkEntry class that you must use: public class MarkEntry{public string StudentNumber { get; set; }public string Name { get; set; }public int Mark { get; set; }public string Module { get; set; }} The function should determine the status as follows: o 0 to 48: return “Fail” o 49: return “Pass (Condoned)” o 50 to 74: return “Pass” o 75 to 100: return “Pass with Distinction”  The function should return an error if no MarkEntry is provided.

In this question, you will create an Azure Function and write unit tests to verify that the functionality is working correctly. Read both parts (i.e. Q.2.1 and Q.2.2) of the question before you start with the implementation. Q.2.1 Create an Azure Functions project, containing a single function. The purpose of the function is to find the country with the highest methane output from a list. Methane and carbon dioxide are two greenhouse gasses that contribute to climate change. Methane emissions are measured in kg/year. The requirements of the function are as follows:1. The function must make use of an HTTP trigger.2. The name of the function should be FindHighestMethaneOutput.3. The function should accept a list of Country objects as input, from either a get or a post operation. Here is the definition of the Country class that you must use: public class Country {public int CountryId { get; set; }public string Name { get; set; }public int MethaneOutput { get; set; } public int…
