Even numbers are numbers whigh are divisible by 2. Therefore, the first even number is 2. A pseudocode which adds the first 100 even numbers can be written thus :
counter = 0
sum = 0
interval = 2
while counter < 100 :
sum = sum + interval
interval += 2
counter +=1
print(sum)
- A counter takes count of the number of values summed
- Initializes a variable which holds the sum of even values
- Since even numbers are divisible by 2; every factor ; increase every added value by 2
- The program ends once counter is 100

Answer: a) 
(b) 
(c) 
(d) 
Explanation:
The formal description of the given sets are as follows :-
a) The set containing the numbers 5, 9, and 27.
(b) The set that contains all the natural numbers less than 2.
(c) The set containing the empty string.
We know that in formal description, the empty string is denoted with 
.
Thus, the required set :
(d) The set containing nothing at all.
The answer is <span>memory. </span>Running fewer applications at once is a way to resolve the bottleneck in <span>memory. </span>Run fewer programs at the same time and restarting a PC regularly, is a good way to clear out its memory.
Explanation:
A brute attack is a method of cracking someone's password/credentials using a predefined set or list of commonly used passwords or from a database leak.
We can prevent our passwords from being brute forced by using a combination of password with no dictionary words and using many symbols and numbers with both upper and lower case characters.
