It doesn't make it faster The current time complexity is O(n), by taking the square root the time complexity becomes O(n^0.5) which is faster. 1 Like |

yusman14: lol...This old language.. It has no application currently If they were taught the right concepts then the language doesn't matter. Programming is like painting, a programming language like a paint brush. Give a bad painter the best paint brush and he'll still produce a bad painting, but a good painter can work with anything. 2 Likes |

Also, the initial value of i cannot be 1, as any number % 1 = 0. This means no number will pass the test. Therefore, i should be initialized to 2 at the start of the loop. |

A faster way is to use Math.floor(Math.sqrt(x)) |

Lol...
Truth is, not everybody needs mathematics to be better programmers, but when you want to take programming to a whole new level, then you'd be needing mathematics and algorithms.
For prime numbers, you'll have to iterate through the numbers less than or equal to half the number, and check if they divide the number.
So, Using javascript
let isPrime = false; let num = x; //choose the number yourself for(let i = 1; i < Math.floor(x/2); i++) { //you can still use parseInt(x/2), it casts it to an integer if(x % i == 0) { isPrime = true; break; } }
You can try and run this code. I didn't run it, 'cause I just typed with my phone. You're supposed to assume the number to be prime initially, with isPrime = true. Then inside the if statement, if a factor is found, you set isPrime to false. |

Maskyy: Wow lots of aspirer programmers and experience ones... I "hello world" you all.
Following the trend from the start till now, have been reading some comments on *YouTube* video as a form of learning for beginners. Nope, this is not right. Don't learn from YouTube, you will hardly see the mistake, which is part of the code learning, sometimes called BUGS.
As a beginner in programming, learn by theory. I repeat it, learn by theory. Read that book until you fall and rise from that mistake, and later you'll understand the "why's" and "how's" of the code.
To all my boss here, Am a software developer, front end precisely. ******No details*****
You love web right, start from here......
1. https://developer.mozilla.org/en-US/docs/Learn/ (start from HTML, CSS , JavaScript...... At this point you can choose your part yourself)
2. **Google search w3school site( cool for everyone and there explanations are superb)
3. Open a github account and Try to understand how github work for a start. Not hard at all but leave it aside if you don't get it easily. That will be later.
4. Get yourself a codepen account. (If you don't know what to do with, leave it aside, later on you will).
5. Get yourself a LinkedIn account if you can. Start building your portfolio from the start. Don't leave it aside. Get use to the network. It's not a social network like fb, instag, its a professional platform.
6. After few training, register with codewar.... Learn by coding. You must code. Yes you must for a better understanding.
7. Freecodecamp is nice. Check it. It may work for you.
Yap... I will recommend these books... 1. Jon duckett HTML and CSS 2. Jon duckett JavaScript and jquery. 3. Eloquent JavaScript (new edition)
Pls afford a premium lesson, either online or offline. There's a greater merit in having a strong tutor.
Also join platform and community that talk about what you do. Either on fb or elsewhere. Try to get to those better than you.
You can find some free books on pdfdrive site (I wish to have such an online library too)
What else friends... Pls feel free to work with templates. Download lots of free templates and check there codes. With that you will learn more.
This should be the first, I don't why I place it here... Algorithm, data structure (some said it's a compt. Science school package. Whatever for non compt. Scie., get books online and understand the little you can at least for a start).
To end the whole talk... Once you embark on this journey, you won't stop learning ooooo. Maybe until you have something to rest on (not deaths but rich enjoyment i.e money$$$). Don't worry, there's too much money in the industry....
If you can trust your ability apply for Andela code competition or internship.
Also apply for site like codewar monthly competition.
Again, I greet all my Seniors here.
I totally agree, but I don't think Eloquent JS is a beginner's book 2 Likes |

Martinez39: My work, using coordinate geometry.
1) Fix the diagram on a rectangular coordinate system such that point O is at the origin and CD lies on the x-axis. Doing this gives the following coordinates: O(0, 0), F(4, 0), D(6, 0), E(-3, 0), C(-6, 0)
2) The equation of the circle that yields the bigger semicircle is
and the equation of the circle that yields the smaller semicircle is
3) the smaller semicircle contains the points F(4, 0) and E(-3, 0) therefore the coordinates of both points satisfies eq. (2) Solving (3) & (4) simultaneously, we will discover that h = ½ and substitution into either (3) or (4) yields k² + (49/4) = r²
4) Observe that point (h, k), O(0, 0) and point B are vertices of a right triangle of sides a, b, and c such that
5) r² = |AB|²/4 |AB|² = 4r² = 96 unit²
|AB|² = 96 unit² Sweeet |

Hi. I'm a science student currently in SS3 with dreams of going to NUN(Nile University Nigeria). I wouldn't have been able to afford it if not for their scholarship scheme. My question is this: is NUN a really good school? The truth is I had never heard of it until a friend told me of the scholarships they award.
Please help a brother make the right choice. Thanks.
