It’s true but everybody knows how annoying CAPTCHA can be. Besides, it fails to work very often. So, you can loose your clients in this way. As a webmaster I recommend to use spam protection that would be invisible for visitors. For instance, https://cleantalk.org/ uses simple plugins for the most popular CMS such as WordPress spam protection plugin, Joomla, Drupal and other plugins. In this way visitors will be more loyal and not annoyed guessing characters or puzzles.

10100100 XOR 11010101 = 01110001.

A common way to detect whether a value is even or odd is to use the AND 1 operation to test if the least significant bit is set.

Combining multiple flags into a single variable can be accomplished via the OR operation.

Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8):
Rudik [331]

Answer:

Given,

P = (22, 1, 42, 10)

Q = (20, 0, 36, 8)

a. Formula for Euclidean Distance :

distance = ((p1-q1)^2 + (p2-q2)^2 + ... + (pn-qn)^2)^(1/2)

Now,

distance = ( (22-20)^2 + (1-0)^2 + (42 - 36)^2 + (10-8)^2) ) ^(1/2)

=( (2)^2 + (1)^2 + (6)^2 + (2)^2 ) ) ^(1/2)

=(4+1+36+4)^(1/2)

=45^(1/2)

Distance = 6.7082

b.Manhattan distance :

d = |x1 - x2| + |y1 - y2|

d = |22- 20| + |1 - 0|

d = |2| + |1|

Decimal numbers are based on __________.
Shtirlitz [24]
