i have question about scratch as you can see in this photo , it request to write a algorithm and Implement the algorithm using scratch 

what i need is a photo of algorithm and photo of scratch implementation  

 

Question 2: (8 marks) Consider a list of unsorted numbers, think about an algorithm to test all the items in the list to check whether there are any two consecutive numbers (even if they are not adjacent) or not. For example 1: List A = [10,7,23,18,45, 24] -> output: true o the output is True because 23 and 24 are consecutive numbers (even not adjacent). For example 2: List B = [24,15,18,18,42, 22] -> output: false o the output of example 2 is False because there isn't any consecutive numbers. Now, answer the following Questions: 1- Write an algorithm to solve the above problem? 2- Can you write a new algorithm that is more efficient than the one you wrote in question1 which does the same job? if the answer is yes you need to write down the new algorithm, if not you need to mention that your solution is the best solution? End of the question
