Check 2.4


  1. Check 2.4
    If the following function is given the number 15, how many times will it loop? Modify the return value of the answer() function with your response.
    def f(n): while n > 1: n = n // 2

    def answer(): # Replace 42 with your answer return 42 import sys def set_certificate(certificate_div_id, certificate): document[certificate_div_id].textContent = certificate def get_student_code(student_code_div_id): raw_student_code = document[student_code_div_id].textContent return window.patchCodeToCheckTimeout(raw_student_code, 'check_timeout();'); class captureIO: def __init__(self): self.captured = [] def get_output(self): out = "" for c in self.captured: out += str(c) return out def write(self, data): self.captured.append(data) def flush(self): pass def make_certificate(student_code_div_id, certificate_div_id): student_code = get_student_code(student_code_div_id) certificate = [] try: capture = captureIO() sys.stdout = capture sys.stderr = capture exec(student_code) output = answer() certificate.append((output, type(output))) except: pass set_certificate(certificate_div_id, str(certificate))
