Please, help me with program logic

Hi, I don't care. I'm fighting over this for the second day. Such a task: I have an integer list with some values, such as 65 and 87. And there is a string in which can be written at all anything, numbers, symbols, characters, letters, and so on, you need to check if this string contains the value from this list. I have no idea how to decide. Please help me

string.Contains() In a loop

Pobiega•7mo ago

a list can contain multiple values thou, so what exactly do you mean by "check if this string contains the value from this list"?

Sorry for my bad English. I mean check whether the string contains only values from list Integer values*

uh so if your list is [65,67] and your string is 65x67 that would fail, because x was in there?

I can give a more clear example if you don't understand me.

Look, I have an integer list. For example, it contains 65, 57, 85. And there is a string: "hei+6528/&9294-65=87%57z" need this string to be checked for whether it contains only numbers from list. Toot if there is something other than 65, 57, 85, in our case it is 6528, 9294 and 87, then returns false. Otherwise, if our line is approximately: "hei+*/&65=%57z", true Now more clear?

ah okay so you want to essentially extract all delimited integers from the string, and make sure all those exist in your list of integers

KirieshkaOP•7mo ago

Yes

An excellent usecase for a parser

Can I just a little more? I don't understand what we're talking about.

Pobiega•7mo ago

well, essentially you want to loop over the string, char by char if its a number, add it to a buffer. if its not, yield the content of the buffer as an int, then clear the buffer

I think I'm starting to understand, a second, I need to check something

Pobiega•7mo ago

var input = "ei+6528/&9294-65=87%57z";
var numbersFound = FindNumbers(input).ToList();
Console.WriteLine($"Found {numbersFound.Count} numbers: {string.Join(", ", numbersFound)}");

var input = "ei+6528/&9294-65=87%57z";
var numbersFound = FindNumbers(input).ToList();
Console.WriteLine($"Found {numbersFound.Count} numbers: {string.Join(", ", numbersFound)}");

should printFound 5 numbers: 6528, 9294, 65, 87, 57 if I understood you correct then, instead of printing, we would just check if all the numbers exist in your list of integers

Finally. Thank you very much for your time. You put me on the right thoughts I could find a solution myself. Thanks for working with me. Thank you very much
