Answer:
18000 seconds or 300 minutes.
Explanation:
In the example given in the question, it is stated that the system uses 32-bit unique salt which is equal to 4 bytes where every digit takes up 1 byte thus forming the 4 digit passwords.
Considering that the passwords are 4 digits, starting from 1000 and up to 9999, there are 9000 possible password combinations.
If Eve has to go through the whole range of possible password combinations and it takes her 1 second to guess 1 password. Then in the worst case scenario, it would take her 18000 seconds or 300 minutes to crack both accounts, assuming that it is possible for them to use the same passwords.
I hope this answer helps.
Answer:
import math
angle = float(input('Enter Angle: '))
shadowLength = float5(input('Enter Shadow Length: '))
tree_height = math.tan(angle)*shadowLength
print('Tree Height = {}'.format(tree_height))
Explanation:
From the equation given, the first step is to derive the equation for calculating the Tree Height.

In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.
The program then prompts the user to input values for angle and shadow length.
The inputted values are converted to floats and used in the equation that was derived for Tree height.
Three height is evaluated and the result is printed to the screen

f = int(input("Enter a number: "))
if(f%7==0):
print("It's divisible by 7.")
else:
if(f<7):
print("7")

print(str(f-(f%7))+", "+str(f+(7-(f%7))))
Answer:
The answer to this question is given below in the explanation section.
Explanation:
You can find a single number or name in a large worksheet containing thousands of numbers and names using the find and replacement feature in excel.
You can use Ctrl+F keyboard shortcut for finding and replacing features. When you press Ctrl+F, a dialog will get open, using this dialog, you can find the required number or name while entering in the search text box. Then, click on the Find button, if the worksheet matches the result, give you the matched result in the yellow highlighted color.
