Zenthe first known correct software solution to the critical-section problem for two processes was developed by Dekker. The two processes, Po and P1, share the following variables: boolean flagl2); int turn; The structure of process Pli==0 or 1) is shown below in Figure 1.1; the other process is P.G==1 or 0). Prove that algorithm satisfies all three requirements for the critical-section problem. do { flag[i)=true; While(flagli])X If(turn==j) { flag[i)=false; While(turn==j) lldo nothing flag[i)=true; } } llcritical section turn=j; flag[i)=false; Ilremainder section } while(true);

Alice, a friend of Mr. Bernard’s, wants to compose a song. She asks Mr. Bernard for help. Although Mr. Barnard knows nothing about music, he finds that the sequence of notes in a numbered musical notation can be expressed as an FSM with input the alphabet {1, 2, 3, 4, 5, 6, 7} (“do”, “re”, “mi”, “fa”, “so”, “la”, “ti”). Alice wants to compose a song that contains the pattern “15” an even number of times. Please draw an FSM that only accepts a sequence of notes that satisfies the above pattern.   Note that you should provide a detailed description of the FSMs in your design to show how it works. Specifically, you should describe the meaning of each state.

This is the question:  Restructure Newton's method (Case Study: Approximating Square Roots) by decomposing it into three cooperating functions: newton, limitReached, and improveEstimate. The newton function can use either the recursive strategy of Project 2 or the iterative strategy of the Approximating Square Roots Case Study. The task of testing for the limit is assigned to a function named limitReached, whereas the task of computing a new approximation is assigned to a function named improveEstimate. Each function expects the relevant arguments and returns an appropriate value. An example of the program input and output is shown below: Enter a positive number or enter/return to quit: 2 The program's estimate is 1.4142135623746899 Python's estimate is 1.4142135623730951 Enter a positive number or enter/return to quit   I will attatch my code as an image.  I have written the code and I really do not know why the program is not accepting it, even though my code returns exactly what the…

Can you please help me solve problem 2?
