Answer:
(b) 7 characters: 4 Numbers, 1 Lowercase Letter, 1 Uppercase letter, 1 Symbol
Explanation:
The best rule that makes a password great is that rule that increases the entropy of the password. The entropy of a password is the measure of how easy it is for the password to be cracked e.g by guessing, by brute force cracking, by dictionary attacks and other related cracking methods.
A rule that makes use of a logical combination of the four types of characters - digits, lowercase letters, uppercase letters and special symbols - gives a greater strength to the password than the rules that just make use of the some of the four types of characters.
Increasing the length of the password too is a great way of increasing the entropy of the password. But then, if there is a trade-off between length and combination, the latter is better.
Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Python, and you can apply a similar method for any programming language.
Answer:
def rightMost(num):
lenNum = len(str(num))
rightNum = num%(10**(lenNum-1))
print(rightNum)
return(rightNum)
Explanation:
In this function we receive an integer number, then we find how many digits this number has, and finally, we find the rightmost digits; the main operation is modulo (takes the remainder after a division), what we want is to take all the digits except the first one, for that reason we find the modulo of the number when divided by ten to the power of the length of the number minus one, for example, if the number is 2734 we divided by 10^(4-1), where four is the length of the number, this way we get 2734/1000 and the module of it is 734.
