Halloween candy // Challenge problem //C#// hidden tests

Question

Disclaimer: this is my first ever try in programming, so please don't be harsh.
https://www.sololearn.com/coach/4?ref=app
I've been trying to solve this problem in C#, and I'm obviously missing something here.
But since tests 3-5 are closed up, I have no means to find out what I'm doing wrong. Can someone explain it to me? Pretty please?
Here goes nothing:
//this how I've tried to solve it
int x = 200;
//100% multiplied by 2 instances
double result = ((double) x/houses);
double xresult = Math.Round (result-0.1);
//googled this one
Console.WriteLine (xresult);

Answer 1

Татьяна // Tatiana
Ceilung rounds up to the smallest whole number that is greater or equal to the given number:
10->10
10.2->11
10.9->11
Rounding rounds to the nearest whole number:
10->10
10.2->10
10.8->11
Did you understand know?

I tried the same, but as I dont know how to ceil in C# I just did something like the following. It is ugly but it works....
int houses;
houses = Convert.ToInt32(Console.ReadLine());
if (houses==10)
Console.WriteLine(20);
else
Console.WriteLine((int)((double) 200/houses)+1);

Pls take care from next time
And instead of copy pasting the text in your code! Copy the code link!

Answer 4

Namit Jain yeah, I've searched for the answer, but somehow missed it. I was able to find explanations on other programming languages, but I'm too new to this, so I couldn't connect the dots in C#.
Alexander Thiem yep, that helped! Thanks, you saved me some google-time 👍

Answer 5

You are welcome ☺️

Answer 6

Татьяна // Tatiana Well,
print(math.ceil(200/int(input())) is Python Syntax!
Python is famous for beeing able to solve !every! problem in a single line if necessary.
c#:
Console.WriteLine((int) Math.Ceiling((double)200/Convert.ToInt32(Consile.ReadLine()));

Answer 7

Татьяна // Tatiana it's a general mathematical thing.
2*100/houses
and
2/(houses) * 100
Are same.

Answer 8

Thank you so much! Ceiling worked. I don't understand the difference, but eventually i will.

Answer 9

~ swim ~ I do exactly know what my code does👍
I did not know how to ceil. Thanks to you I know it now. But as the only failing testcase was 10 I just did not want to google how to ceil, as my version solved the test😂😂

Answer 10

houses = int(input())
#your code goes here
import math
print(math.ceil(2/(houses)*100))

Answer 11

KUMAR SHANU hmmm, I might be wrong here, but isn't it supposed to be 2*100/houses?

Answer 12

Татьяна // Tatiana
Ohh ya
I forgot
import math
print(math.ceil(200/int(input())))

Answer 13

Namit Jain that's why I love SoloLearn ! I would've never come up with oneliner like this myself. Thank you 😎👍
Upd: tried this, can't make it work. Google says x=int (input ()) is from Python sintax.

Answer 14

Alexander Thiem well, the whole thing forced me to learn many unexpected things 🙈

Answer 15

Namit Jain it looks perfect , but aren't we need ceiling, so if there are (for example ) 3 houses, output would be 67, not 66?
