6. Given an random number generator rand5() that generates a uniform random integer in the range 1, 5|, design an algorithm for rand7() that generates a uniform random integer in the range |1, 7|. You can only call the API rand5(), and you shouldn't call any other AlPI. What is the expected mumber of times you call rand5()? How small can you make this expected mumber?
