Temperatures puzzle discussion

Puzzles
#160

I think you forgot to read the temperatures from standard in.

#161

Question:

-I’m using VB.net
-what how is the data “temps” and how can I convert it into an integer array?

#162

Split the string by ’ '(space), then parse the elements of the array to use them as Integer

#163

Hi,
Tell me please.
I used array.Split(’ '); to record values from a string to an array. Then used Array.ConvertAll to convert string array to int array.
Now I have array that records the data from the variable temps.
( string temps = Console.ReadLine(); // the n temperatures expressed as integers ranging from -273 to 5526)

How can I identify the nearest number to 0 considering the conditions of the game.
Maybe there is some kind of function?
I do not understand how to compare the same number of positive and negative values.

Thank you!

#164

That’s your task. You have to write that function.

#165

Bonjour,
Je code en C et j’ai un souci.
Est ce que le programme doit renvoyer la température ou son indice dans le tableau ?
Car dans la description du puzzle on parle de tempĂ©rature, par contre pour rĂ©ussir les tests cases il faut renvoyer l’indice de la tempĂ©rature dans le tableau.

Est ce normal ?

#166

It’s the temp.

#167

I modified the stub code to this:

var n = parseInt(readline()); // the number of temperatures to analyse
var temps = readline().split(' '); // the n temperatures expressed as integers ranging from -273 to 5526

Now when I try to run through this array as

var closest = temps[0];
for (i = 0; i < n; i++){
   if ((temps[i] > closest)&&(temps[i] < 0)){
       closest = temps[i];
       printErr("It's closer!");
   }
}

The check fails for the values [-5, -4] in test 2. Why is this seeing -4 as being lesser than -5?

#168

You works with string. so -4 < -5

#169

My first and second IDE tests (in C) appear to be broken.

For the first: I’m having it print all the values in the array before doing it. I’m getting:

49
32
45
0
-1
Result: -1

But it says

Expected: "1"

For the second: I’m getting:

45
5527
53
32
45
45
52
32
45
50
0
8
32
Result: 8

But it says

Expected: "2"

Neither of these make sense.

Pretty sure this puzzle while using python has a few bugs and it’s rather annoying.
Bug 1:
As written in the “Game Rules” -
“Line 2: The N temperatures expressed as integers ranging from -273 to 5526”
This is inaccurate, the N temperatures are expressed as a string, not as integers. you have to split the string into an integer list.

Bug 2:
The Validator returns the following as False:
“It works when inputs contains only negative numbers: : {-15 -7 -9 -14 -12} -> -7”
Last time I checked, -7 is the correct value
 wtf? and this is made even more confusing when the second to last validation passes

“It works with two negative temperatures that are equal: {-10 -10} -> -10”

Bug 3:
I also fail test 2 and 3 but have no idea why
 I have a statement in my code that says

templist = map(int, temps.split(' '))
templist.sort()
cval = min(templist, key=abs)
if n == 1:
    cval = templist[0]

Which is I would think is pretty freaking standard, if there is only 1 value in the list
 just pass that value
 it works on my IDE
 why not the validator?

#171

I’m having almost the exact same issue in Python.

I can pass all three tests, but the validators fail on the following two:
It works when inputs contains only negative numbers: : {-15 -7 -9 -14 -12} -> -7 250
When two temperatures are as close to 0, then the positive wins: {15 -7 9 14 7 12} -> 7 750

Why would the only negative numbers test fail and the two same negative numbers test pass? Isn’t that basically the same thing?

#172

Hello CodinGamers,

Temperatures was one of our first puzzles and there is not enough tests in IDE, plus validator names are not helping to understand what is going on.
As an example: “{-15 -7 -9 -14 -12} -> -7” is the name of a test. I mean that “-> -7” is not meaning your output is -7 on this test case.

We will work on this puzzle next week.

#173

Ide test cases updated and validators renamed.

These modifications should avoid issues.

#174

You beautiful bastard. Thanks for the help!

#175

If anyone else is having problem whit the -10 -10 test, it seems the result must be positive even if both temperatures are negative.

#176

I can assure you that in that case, the result is negative.

#177

Bonjour,
J’ai un petit souci avec le tableau de tempĂ©ratures: c’est un tableau de caractĂšres, alors, comme ce n’est pas bien pratique en C, je le transforme en tableau de nombres (int) avant de faire les test.
Pour cela, je parcours le tableau en faisant une petite boucle while(temps[i]!=’\0’), vu qu’un tableau de caractĂšre est censĂ© toujours se terminer par ‘\0’

Seulement voilĂ , aprĂšs avoir passĂ© les diffĂ©rents tests, je m’aperçois que cette boucle fait un “tour” de trop. Comme s’il y avait quelque chose entre le dernier caractĂšre (un chiffre, donc) et la fin du tableau. Quelque chose qui n’est pas un espace et qui me renvoie un nombre qui n’a rien Ă  voir avec ce que j’attends


Pour palier Ă  ce problĂšme, j’ai trichĂ©: j’ai transformĂ© ma boucle en while(temps[i+1]!=’\0’)
Je m’arrĂȘte donc quand le caractĂšre SUIVANT est la fin du tableau, et je ne traite pas le dernier caractĂšre avant la fin.
Cette mĂ©thode marche trĂšs bien
 sauf pour le test n°2. Dans ce test, le tableau semble mieux dĂ©fini (c’est Ă  dire qu’il s’arrĂȘte bien juste aprĂšs le dernier caractĂšre) et du coup, comme ma nouvelle boucle s’arrĂȘte avant, je “zappe” le dernier chiffre (1337 devient 133
)

J’aimerais donc savoir comment ces tableaux de char sont dĂ©finis exactements, pourquoi il y a “quelque chose” entre le dernier caractĂšre et la fin, et pourquoi ce quelque chose n’est pas dans le test 2.

À noter que cela n’empĂȘche pas la rĂ©ussite de tous les tests, puisque la derniĂšre valeur n’est jamais la plus proche de 0.

Merci

#178

can someone please help me?
i have my code set up to where i have to manually change the code each test, and it will pass all but the last one, where there are no inputs.
here’s my code so far


// function for finding closest number to 0

function closest(num, arr) {

var curr = arr[0];
var diff = Math.abs (num - curr);
for(var val = 0; val < arr.length; val++){
    var newdiff = Math.abs (num - arr[val]);
    if(newdiff < diff){
        diff = newdiff;
        curr = arr[val];
    }
}
return curr;

}

// test cases in one array

var i = 0;

array = [

simpTest = [1, -2, -8, 4, 5],
onlyNeg = [-12, -5, -1337],
chooseRtemp = [42, -5 * -1, 12, 21, 5, 24],
chooseRtemp2 = [42, 5, 12, 21, -5 * -1, 24],
complex = [-5, -4, -2 * -1, 12, -40, 4, 2, 18, 11, 5],
noTemp = []
];

n = array.length[i]
number = 0
print(closest(number, array[0]));

is there a way to have the code do each array by itself, for all the test cases??

#179

Perdonad pero me da un error que dice que tengo mi codigo como Hard Coded aun pasando las pruebas.
Aqui esta mi codigo
[EDIT: NO FULL CODE]

Alguien me puede decir cual es el problema?
