What would be the easiest way (if possible with tidyverse) to multiply each columns x1:x10 with their respective vector. For example: the first row of the new table would be: age = "one", x1 = x1 * 1, x2 = x2 * 2, x3 = x3 * 9, x4 = x4 * 4...etc

I have a folder inside my repository that has the following name test.1.2.3. However, I'm unable to add the folder to my git commit. If I change the name to test-1-2-3 it works as expected and the folder is added to the git commit.

If I add the folder to the repo and run git add .;git commit -m "change made" the command returns:

I'm solving the example probation problem in Python and had only partial success so far (passed 30 test cases, wrong answer in the 31st). The test cases themselves are not disclosed.

Description.

A network of n nodes connected by n-1 links is given. Find two nodes so that the distance from the fatherst node to the nearest of those two would be minimal. If several answers are possible, any of them will be accepted.

The input is given as a list of pairs of numbers. Each number represents node, pair is the connection between two nodes. The result should be the list of two nodes.

Example 1 in = [[1, 2], [2, 3]] result = [3, 1]

Example 2 in = [[1, 2], [3, 2], [2, 4], [4, 5], [4, 6]] result = [2, 4]

My solution.

The net will always be a tree, not a graph. For the above examples the corresponding trees will be:

example 1

below is the code for print a linked list

I'm asked to create a Regex to validate phone numbers with these rules:

Phone: contains 9 to 11 digits. Space, dot, and dash can be used to group/separate digits for easy reading. However, space, dot, and dash cannot be positioned at the beginning or at the end of a phone. Furthermore, they cannot be positioned next to each other. Valid phone examples: 0123456789, 0-1-2-3.4.5 6.7-8-9, 012.345-6789. Invalid phone examples: 01234567890123 (too long), (0123)456-7890 (parentheses are not allowed), 012--3456789 (2 dashes are next to each other).

Since the phone number is so free of form, I'm having a hard time figuring out the correct Regex for it. It doesn't help that I'm still super new to JS so any hint or help would be much appreciated.

When manipulating user input like - 12345 - to add dashes inbetween chars like - 1-2-3-4-5, I know that we can run something like:

The SVG (with animation) works perfect on .HTML file. But when I use it in Nuxt.js,

I would need help on regex for accepting any 7 digit to 10 digit number (no decimals) along with hyphen or spaces in between any where in the digit.

For example ,

Below are valid scenarios

I have this question for a practice assignment:

In Cee-lo, having a roll where two of the three dice have the same value is called a point. This is the second weakest dice roll, only stronger than a 1-2-3. Complete the is_point() function that takes a single string parameter dice_str consisting of three dice values. If the dice rolled (as represented by the dice_str) have two of the three dice with the same value, the function should return True. Otherwise, the function should return False.
