Question

python

Answer the following question without running the code. The procedure isMyNumber is used to hide a secret number (integer). It takes an integer x as a parameter and compares it to the secret number. It returns:

• -1 if the parameter x is less than the secret number

• 0 if the parameter x is correct

• 1 if the parameter x is greater than the secret number

The following procedure, jumpAndBackPedal, attempts to guess a secret number. The only way it can interact with the secret number is through the isMyNumber procedure explained above.

def jumpAndBackpedal(isMyNumber):
    '''
    isMyNumber: Procedure that hides a secret number. 
     It takes as a parameter one number and returns:
     *  -1 if the number is less than the secret number
     *  0 if the number is equal to the secret number
     *  1 if the number is greater than the secret number
 
    returns: integer, the secret number
    ''' 
    guess = 1
    if isMyNumber(guess) == 1:
        return guess
    foundNumber = False
    while not foundNumber:
        sign = isMyNumber(guess)
        if sign == -1:
            guess *= 2
        else:
            guess -= 1
    return guess

Unfortunately, the implementation given does not correctly return the secret number. Please fix the errors in the code such that jumpAndBackpedal correctly returns the secret number.

Answer 1

Code Starts from here
___________________________________________________________________________

def isMyNumber(x):

    secret_number =199;

    if x ==secret_number:

        return 0

    if x > secret_number:

        return 1

    else:

        return -1

        

def jumpAndBackpedal(Number):

#Change the jumpAndBackpedal Functions parameter name because it was creating error.

#"TypeError 'int' object is not callable" It probably means that you are trying to call a method when a property with the

# same name is available. If this is indeed the problem, the solution is piece of Cake..

    guess = 1

    

    while True:

     if isMyNumber(guess) == 0:

        break

     else:

      if isMyNumber(guess) == 1:

         guess=guess-1

      if isMyNumber(guess) == -1:

         guess=guess+1

    return guess

jumpAndBackpedal(5)
