Modify the recursive Fibonacci function to employ the memoization technique discussed in this chapter. The function creates a dictionary and then defines a nested recursive helper function named memoizedFib. The base case is the same as before. However, before making a recursive call, the helper function looks up the value for the function’s current argument in the dictionary (use the method get, with None as the default value). If the value exists, the function returns it. Otherwise, after the helper function adds the results of its two recursive calls, it saves the sum in the dictionary with the current argument of the function as the key. Also use the Counterobject discussed in this chapter to count the number of recursive calls of the helper function. Included code:def fib(n):"""Returns the nth Fibonacci number."""if n < 3:return 1else:return fib(n - 1) + fib(n - 2)def main():"""Tests the function with some powers of 2."""problemSize = 2print("%4s%12s" % ("n", "fib(n)"))for count in range(5):print("%4d%12d" % (problemSize, fib(problemSize)))problemSize *= 2if __name__ == "__main__":main()

Pthreads programming: create and terminate a thread write a c++ program that creates a thread. the main will display a message “hello world from the main”. the main will create a thread that will display a message “hello world from the thread” and then terminates with a call to pthread_exit()
