Found this to be an issue with SELinux that is not allowing httpd network connections. Executing: setsebool -P httpd_can_network_connect=1 Solved the problem. solved PHP not connecting to Remote MySQL [duplicate]
“Which is better” is always a matter of opinion. In your particular application, is execution time or memory use more of a problem? Then optimize for that aspect. In terms of leetcode, I understand it’s a sort of quiz, but for numbers that small, my response is “who cares?”. I don’t care about an execution-time … Read more
When you’re using Scanner.nextInt() the input is expected to be an integer. Inputting anything else, including a real number, will throw an InputMismatchException. To make sure invalid input doesn’t stop your program, use a try/catch to handle the exception: int num; try { num = sc.nextInt(); // Continue doing things with num } catch (InputMismatchException … Read more
If the original value is in seconds as in 5.323 for five seconds and 323 milliseconds, you can convert it to a dateserial value by dividing it like this: dataserial = seconds / 24 / 60 / 60 Append the resulting value to the spreadsheet and format the cell or the whole column as duration, … Read more
You can do something like this const data = [{date: 2021,name: ‘New York’,price: 452}, {date: 2020,name: ‘New York’,price: 452}, {date: 2021,name: ‘Oregon’,price: 452}] const result = Object.values(data.reduce((res, {name,…rest}) => { return { …res, [name]: { name, values: […(res[name] || {values: []}).values, rest] } } }, [])) console.log(result) solved JavaScript: Convert array of objects into array … Read more
You generate the CC number once and display it multiple times. Instead, put the CC generator in the loop. from random import choices from string import digits for _ in range(5): cc_digits = choices(digits, k=16) cc_number = “”.join(cc_digits) space = ” “.join(cc_number[i:i+4] for i in range(0, len(cc_number), 4)) print(space) 1 solved How do I print … Read more
Here is a test application to show you the trace of the program’s execution (requires Java 11 due to the use of String#repeat(int)): public class Main { private static int depth; public static void main(String[] args) { foo(0); } public static void foo(int n) { printDebug(“Invoked foo(” + n + “)”); if (n < 2) … Read more
First you have to understand what the price of something is. The real price of something is how much people are willing to pay for it. If the seller is willing to sell at the price the buyer is willing to buy then a sale happens – the sale also defines the price of the … Read more
In C++, you can utilize lambda functions to achieve something similar: #include <iostream> using CmpFunc = bool(float, float); CmpFunc* condition(char op) { switch (op) { case ‘>’: return [](float a, float b) { return a > b; }; case ‘<‘: return [](float a, float b) { return a < b; }; case ‘=’: return [](float … Read more
Bitwise XOR assignment (^=) The bitwise XOR assignment operator (^=) uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable. Source: MDN 1 solved what does ^= mean in js [duplicate]
No, its no. The ARM instruction set may be more limited compared to the x86 instruction set but this has nothing to do with the architecture of the processors. The ARM instruction set is not a subset of x86 instructions. They are encoded differently and the processor executes them in a different way. The registers … Read more
Assuming that you want to name your keys as key1, key2.. and so on when a key is not found: l = [[‘a’,1], [‘b’,2], [3], [‘d’,4]] d = {} i = 1 for x in l: try: d[x[0]] = x[1] except IndexError: d[‘key’+str(i)] = x[0] i += 1 print(d) Output: {‘a’: 1, ‘b’: 2, ‘key1’: … Read more
t=”POST / HTTP/1.0\r\nAuthentication: Bot {token}\r\nHost: discord.com/api/guilds/{702627382091186318}/channels\r\n\r\n” This is not a valid HTTP request. You essentially send (line breaks added for clarity): POST / HTTP/1.0\r\n Authentication: Bot {token}\r\n Host: discord.com/api/guilds/{702627382091186318}/channels\r\n \r\n But a correct POST request would look like this instead: POST /api/guilds/{702627382091186318}/channels HTTP/1.0\r\n Authentication: Bot {token}\r\n Host: discord.com\r\n Content-length: … \r\n <body, where size matches … Read more
Did you investigate what the real bottleneck is? This is all about upload speed, and the most obvious cause is that the clients have not enough bandwidth. Even if they use a fast ADSL, they could still have low upload speed (the “A” in ADSL stands for “Asymmetric”, i.e. fast download, but slow upload). For … Read more
Your question leaves a lot of information to the imagination, but for instance this will swap those two words, once a second, in an element with the id “target”: var target = $(“#target”), word = target.text(); setInterval(function() { word = word === “hello” ? “glad” : “hello”; target.text(word); }, 1000); Live Example | Source Or … Read more
