This is really tough thing!

Question

Can u guess quickly in the given time that it's exponentional function & u have to do 2^3==8 ?
I guessed but it was too late:-))) Some quizzes are just freaking me out:-)

function expo($b, $e) {
if ($e==0)
return 1;
$result=$b;
for($i=1; $i<$e; $i++)
$result*=$b;
return $result;

}
echo expo(2, 3);

Answer 1

This is pretty simple and i'm not so good in PHP (i can't see that syntax), but i can understand what you want to say, i lost many challenges because of math quizzes!

I thought something like: "Can a human calculate all this stuff in this short time"...?

In most cases yes, generally there was tricks to solve them, so i made a private code where i added most difficult challenges with a short explanation.

This helped me to remember and understand something more, maybe can be helpful do the same. :)

I updated this code for two days, then i understand i'm too lazy to keep this project updated, take it as a reference:

@Maz Thank's Maz! Opposite to you I don't like JavaScript because of the ugly data types conversion, prototyping instead of normal OOP and many other things. However I really like JQuery lib & React.js lib! Strange thing:-)))
