As we change password when

1. we forgot the previous password.

2. when the previous password is leaked due to some reasons.

In case 1 we can change the password to the same as well with no change the problem will be solved but for case 2 at least one or for more safety all characters should be changed.

what type of clause must you always use with DEKETE or UPDATE to avoid inadvertently changing data elsewhere in the database

Shkiper50 [21]

While you’re using the DELETE or UPDATE to change the data in any database like MySQL or ORACLE, the WHERE clause can be used to avoid inadvertently changing data everywhere.

Explanation:

The WHERE clause checks the condition and the changes mentioned by the DELETE or UPDATE command will be done if the condition is true. There are also other clauses like HAVING, IN which will have range either inclusive or exclusive.

It is also noted that in MySQL, there is a method called WorkBench which enables safe mode and doesn’t execute statements without the WHERE clause.

Give an example of a language L such that |L|=5 and |L^2|=16.

Basile [38]

Answer:

He can define pas follows: Let P be defined on the set of languages accepted by some Turing machine M. Let it be True if 10 ] is 5 and False otherwise.

Explanation:

The domain of P is the SD languages since it is those languages that are accepted by some Turing machine H. P is nontrivial since P({ a, aa, aaa, aaaa, aaaaa, aaaaaa, b, bb, bbb, bbbb, bbbbb, bbbbbb } ) is True and P ( 5 ) is False.

Thus {< M> is a Turing machine and I L I - 5 and I L I - 16 }

Are you concerned that strangers may have access to the personal information you share on social media platforms? Why or why not

GuDViN [60]

It makes me a little uneasy at times, yes, but I know that they cannot find me unless I share way too much.
Hope this helps~!

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera

aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

num = nums.rstrip('\n')

mylist.append(int(num))

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

mylist.append(int(num))

The following counts the rates in the file and also sum them up

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))
