QUESTION
I'm trying to find Fortnite and return fortnites appversion and path. I dont know if the user is gonna have other apps/how many/what they are. I'm trying to do this in C#. I've tried looping through all of the InstallLocations but the user may have alot.
...ANSWER
Answered 2021-May-09 at 16:10I don't think you can do better than going through all the items in terms of computational complexity without having to use complicated data structures, so just loop through all the AppName.
QUESTION
I'm very new to javascript and working on making a random generator that runs in a browser, and I think I have things mostly figured out, except I can't figure out how to ensure there are no repeats between random strings.
I was thinking maybe removing the first result from the array so the second can't pick it (preferable, because in the final code there will be multiple variables pulling from the same array in multiple different configurations, and several arrays being pulled from in this way, but I don't know if that's possible?), or maybe having the second one rerun until it gets something unique.
however, I, uh, don't know how to do either of these things, and no amount of googling has given me anything both relevant and understandable enough (as a beginner) for me to successfully apply ^^; any help?
this is a simplified version of my code to just include relevant stuff, let me know if I need to provide more
...ANSWER
Answered 2021-Feb-03 at 20:14Here's a basic solution. You can generate an index of the second candis while it is equal to the first one.
QUESTION
I am currently setting up an application with three separate buttons, each which is supposed to randomly select an element from an array specific to that button. I've successfully coded it with individual functions for each button, but I was wondering if there is a way to condense it into a single function that can apply to all three buttons.
This is my current Javascript:

QUESTION
Here's this program, where I have to implement a function that will check whether all the alphabets from a to j (converting all the alphabets to lowercase) has appeared at least once in the given string or not. If all of these alphabets (a to j) appear at least once, then the result will be 5. If any one of the alphabets (a to j) is not in the given string, then the result will be 6. Finally, have to return this result and print the statement, "Chelsea is the best club in England" that many times.

QUESTION
Why do I get an overflow exception even if I apply the unchecked
operator on an expression?
ANSWER
Answered 2020-Jun-01 at 11:42I managed to reproduce this issue with the simplified code below. It seems to me like a bug, or at least as an undocumented limitation of the Aggregate
method. It fails after enumerating a number of around Int32.MaxValue
elements.
QUESTION
I'm sorry for asking a very stupid question. It should be very easy but I'm not able to do this. I'm creating a minimal working model on stackblitz. So, I've a string array containing some information about me (say). I want to display them one by one using ngFor
. But there will be some elements whose strings are very long.
For eg: The string is:
Apple, Ball, Cat, Dog, Elephant, Fish, Goat, Hen, Ink, Jackal, Kite
The displayed text should be:
Apple, Ball ...
That means after the second comma ,
or may be after certain characters, say 15 characters, it should be ...
because the original text is occupying a large width.
I tried these methods:
- slice(start, end)
- substring(start, end)
- substr(start, length)
But these methods will permanently cut short the text. I don't want that. Hope I was able to explain the problem. Please correct me. Here's the stackblitz.
...ANSWER
Answered 2020-Apr-02 at 18:25You can derive your own pipe EllipsisPipe
from SlicePipe
. In the code below, the derived pipe calls super.transform
to apply slice:0:maxLength
, and appends the ellipsis if the original string is longer than maxLength
. Please note that super
refers to the parent class SlicePipe
.

Answered 2020-Mar-17 at 03:16Declare ListItem as an struct instead of a class, this way the view will be notified when isFavorite
changes. And just a little suggestion; you can use toggle to change the value of a boolean: self.list.items[index].isFavorite.toggle()
