Given a string nums, which contains only digits, and an array of numbers predefinedNumbers,
add colons in nums to construct a new string, where each number between colons is a valid number from predefinedNumbers.
Return all possible strings.
EX:
nums = “143163421154143”
predefinedNumbers = [“21154”, “143”, “21154143”, “1634”, “163421154”]
makeNumSentences(nums, predefinedNumbers)
Output:
[
“:143:1634:21154:143:”,
“:143:163421154:143:”,
“:143:1634:21154143:”

I have the following code that animates the background-position property so it “slides” to a different color afterwards. My problem currently is how to reverse it. Most of the examples I’ve seen is around hover; this one though is from a context of a click event. Any ideas how I can reverse the animation on re-toggling it?
With Object.keys method you can inspect all object properties, let’s say you create an sdk and want to hide some internal properties, how to prevent Object.keys to get access to all properties somehow ?
I need help to make the html input pattern to work correctly with the following regexp:
/^([0-9]+(.[0-9]*[1-9]|);)*[0-9]+(.[0-9]*[1-9]|)+$/mg
This expression only allow a infinite group of positive numbers, with or without a decimal fraction marked with a point, separated by semicolon. For example:
23;23.3;444
I tried:
document.querySelectorAll("input")[0].pattern="^([0-9]+(.[0-9]*[1-9]|);)*[0-9]+(.[0-9]*[1-9]|)+$";
But in the html pattern, allows:
23;23.3;444;44-4;44,4
Using JS works perfectly:
regex = /^([0-9]+(.[0-9]*[1-9]|);)*[0-9]+(.[0-9]*[1-9]|)+$/mg;
regex.test("541.4;4;3;3.3;33;33;45.5;443;4"); //true
regex.test("541.4;4;3;3.3;33;33;45.5;4-43;4"); //false
Any ideas how to fix this html pattern? Thank you.
I have the following code and I’m trying to generate public-private key:
const openpgp = require("openpgp")
const generateKeyPair = async () => {
const { publicKeyArmored } = await openpgp.generateKey({
userIds: [
{
name: 'Jon Smith', email: '[email protected]',
comment: 'This key is for public sharing'
}
],
curve: 'ed25519',
passphrase: 'super long and hard to guess secret',
});
console.log(publicKeyArmored);
}
But I’m getting this error. Any idea how to solve it:
(node:17380) UnhandledPromiseRejectionWarning: Error: Unknown option: userIds

</html>Im Accessing a file from my device storage using HTML file input then I read that file as a stream.
const stream = myFile.stream()
const reader = stream.getReader();
//actually I use this each time I want to read more data from the stream
reader.read().then(function({ done, value }) {
const bufferSizeInBytes = value.length // I want to limit this to 1000 bytes as max value
})
Another question that’s confusing me, why do we get different size of the buffer on each read, does it depend on the available memory or cpu or how does it actually work? if it depends on the memory we would be able to read the whole stream in one single read since the file is around 100 mb and my available memory is around 6GB , but actually it took many reads what made me think that the memory is not the only factor behind this operation.
any help would be much appreciated.
I am very new to Ramda and have got stuck in a problem. I need to get response from an api and pass it to next function but that same response needs to be used again at a later stage in the same compose. How can I save its value in that ramda func scope so it can be re-used again?
const getData = (req, ctx) => R.compose
(
R.andThen(... do some action using response from callSomeApi_2 and prop2)
, R.andThen(callSomeApi_2(req, ctx))
, R.andThen(R.map(R.prop('prop1'))) // response has prop1 and prop2 where prop2 is needed after getting response from callSomeApi_2
, callSomeApi_1(req, ctx)
);
How can this be achieved?
I retrieve data from data from database using ajax call. In my code can not access parameter of parent ajax call request to child ajax request call. I can see error in compiler. I can try to put asyc: false in child request but using async i can access parameter but child ajax call only work one time.

I am calling an API for updating Project name, description and using ID. I have a PUT request that updates all the data. But I want to update only Project name and description. I am not able to perform the PATCH call provider. Can someone tell me how to call the PATCH request
thanks.
This is my PUT request. And I want PATCH request
put(apiUrl, data) {
const apiURL = environment.endPointUrl + apiUrl;
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
AuthenticationKey: `${CryptoJS.AES.decrypt(
localStorage.getItem('UAuthToken') == null
? ''
: localStorage.getItem('UAuthToken'),
environment.EncryptionKey
).toString(CryptoJS.enc.Utf8)}`,
}),
};
return this.http.put(apiURL, data, httpOptions);
}
This is my Service.ts
UpdateProject(data){
const apiURL = 'http://192.168.1.22:8080/TestExpress/projects/updateProject/projectDescription/projectId/projectName';
return this.callProvider.put(apiURL, data);

I have a textbox to which I have assigned a CustomValidator which has a ClientValidationFunction=”txtcheck”
ASPX:
<asp:TextBox ID="txt1" MaxLength="10" CssClass="class1" Width="90%" runat="server"></asp:TextBox>
<asp:CustomValidator runat="server" ID="valtxt1" ControlToValidate="txt1" ValidateEmptyText="true" ValidationGroup="Save" Display="Dynamic"
ClientValidationFunction="txtcheck" Font-Italic="True"></asp:CustomValidator>
<asp:Button ID="btnSave" Text="Save" CausesValidation="True" runat="server" ValidationGroup="Save" OnClientClick="show()" UseSubmitBehavior="false" />
Javascript :
The alert messge is mandatory as it is required.
function txtcheck(source, args) {
Alert('incorrect value');
args.IsValid = false;
}
function show(){
var validated = Page_ClientValidate('valSave');
if (validated) {
-- show some data.
}
}
On click of Save Button I do a Page_ClientValidate to check other controls.
The issue is, on click of Save; txtcheck() is getting called twice.
Once via the CustomValidator & other when I do the Page_ClientValidate. Due to this the Alert message is also shown twice.
Pls guide as to how to call the txtcheck() only once & show alert once.
Any help is greatly appreciated.
