Write a recursive Ce program to sobve thefollowing problem : Problem 4a P(1) 3 P(2) = 4 P(n) P(n-1)+P(n-2) for n>2 To test-output for P(4)-11 P(6) 29 and P(7)-47 Hint: main shall call a function int par(int n) that returns 3 if n=1, it returns 4 if n = 2, and it returns par(n-1)+par(n-2) if n>2 Provide screen of your output for n-5 or P/5 Sample Output (Your name will replace mine & yours will be P(5) Cindy shows P(7) has 47 units Problem 4b: Note: the numbers just above the ovals are the return values. You may hand draw&scan or use Paint or Visio or Googledraw, etc to create this and paste into your document. Draw a call tree for P(S). This should look similar to Figure 2.30 in the textbook
