Answer:
A Direct Current (DC) electromagnetic field refers to a constant or static DC electric or DC magnetic field emission which has a frequency of 0 Hz. DC magnetic fields can also be created from a DC power source of electricity such as battery power, solar power, and wind power.
Answer:
(a) someFunc(3) will be called 4 times.
(b) For non negative number n someFunc method calculates 2^2^n.
Explanation:
When you call someFunc(5) it will call someFunc(4) two time.
So now we have two someFunc(4) now each someFunc(4) will call someFunc(3) two times.Hence the call to someFun(3) is 4 times.
someFunc(n) calculates someFunc(n-1) two times and calculates it's product.
someFunc(n) = someFunc(n-1)^2..........(1)
someFunc(n-1)=someFunc(n-2)^2..........(2)
substituting the value form eq2 to eq 1.
someFunc(n)=someFunc(n-2)^2^2
.
.
.
.
= someFunc(n-n)^2^n.
=2^2^n
2 raised to the power 2 raised to the power n.
Explanation:
AIAI or artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning and self-correction. Some of the applications of AI include expert systems, speech recognition and machine vision. Artificial Intelligence is advancing dramatically. It is already transforming our world socially, economically and politically.
AI was coined by John McCarthy, an American computer scientist, in 1956 at The Dartmouth Conference where the discipline was born. Today, it is an umbrella term that encompasses everything from robotic process automation to actual robotics. AI can perform tasks such as identifying patterns in the data more efficiently than humans, enabling businesses to gain more insight out of their data. With the help from AI, massive amounts of data can be analyzed to map poverty and climate change, automate agricultural practices and irrigation, individualize healthcare and learning, predict consumption patterns, streamline energy-usage and waste-management.
ASCII is an agreement on which number represents which typographic character. Using this table you can look up the number of any character. For instance, "A" has 65, but that is a decimal. Next step is to represent this decimal number in hexadecimal. You can do that by taking the divisor and remainder of a division by 16. Numbers beyond 9 are represented as a through f. Hexadecimal numbers are commonly prefixed by "0x" to make them recognizable.
So "A" = 65 = 4*16+1 = 0x41
And "Z" = 90 = 5*16+10 = 0x5a
There are ASCII tables that have the hexadecimal value in them, to make the task easier (www.asciitable.com).
If you want to do this programmatically, you can write something like this (node.js):
console.log( Buffer.from('AZ', 'utf8').toString('hex'));
Note that the 0x prefix is not shown here.
