As part of a code review a colleague recommended using a type rather than an enum. Whilst making the changes we found an issue neither of us expected. We’d expect scenario one and two to throw compiler and/or intellisense errors as one of the values does not exist on the type. However, after testing we… Read More Template literal throws errors in some scenarios but not others
I’m trying to use reduce function in order to find the max length array in arrays so I tried this approach at first but it didn’t work const arrays = [[1],[3,3,4],[3,4],[4,5],[6]] let maxLength = arrays.reduce( (acc, cur) => { return acc.length > cur.length ? acc.length : cur.length }) console.log(maxLength) // output : 1 so I… Read More How Reduce function really work in JavaScript?

Consider the following: #include <iostream> #include <variant> int main () { std::variant<int, float> foo = 3; if(foo == 3) { std::cout << "Equals 3\n"; } } Godbolt demo here This does not compile because of the foo == 3: <source>:7:12: error: no match for ‘operator==’ (operand types are ‘std::variant<int, float>’ and ‘int’) 7 | if(foo… Read More Why does operator==(std::variant<T, U>, T) not work?
I am new to c. My Question. Why do some numbers end up negative when the value was positive? Why do some small numbers end up with a huge magnitude when typecast to unsigned? #include <stdio.h> #include <stdbool.h> #include <limits.h> void typecast(int a) { unsigned b = (unsigned) a; unsigned char c = (unsigned char)… Read More Can Some one explain why I get these output?
I have a function that repeatedly calls another function. The second function has a bool parameter that changes the way it behaves, so when I call the first function I want to have a parameter that specifies the way the second function behaves. void Function1(int n, bool differentBehavior = false) { int a = Function2(n,… Read More Call function with a parameter from another function
Lets say we got date and time to a log in the format of 2022-05-18-11:57:140100 I need to remove seconds from this time. It means the final output should be like 2022-05-18-11:57 I tried the following echo "2022-05-18-11:57:140100" | rev | cut -d/ -f6- | rev`:" this was not successful and I have no idea… Read More cut command top remove seconds from time. shell scripting
Hope someone can help explain why I keep getting the following error in Python.

For me For Loops and ForEach Loops are two of the best ways to handle and display large data. The issue is I want to add an eventListener to a loop and you immediately run into issues. Here is my code, it loops through an API Provided Array and creates HTML Divs perfectly. Near the… Read More Is it possible to add an eventListener in a for loop, if so, how would you implement it?
I am working on LeetCode problem 111. Minimum Depth of Binary Tree: Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. Note: A leaf is a node with no children. I have used a… Read More Minimum Depth of Binary Tree – returns None
