2 Paper Strip Coding Challenge

You are given two paper strips. On each strip, numbers (1,2,… N) are written in random order. Cut the original paper strip into several pieces and rearrange those pieces to form the desired sequence.

Write a function, efficiently with respect to time used, returns the minimum number of cut pieces needed to perform the described operation.

For example, the following code should display 3 because the pieces used should be (1), (4, 3) and (2):

int[] original = new int[] { 1, 4, 3, 2 }; int[] desired = new int[] { 1, 2, 4, 3 }; Console.WriteLine(PaperStrip.MinPieces(original, desired)); 

Another example, the following code should display 5 because the pieces used should be (1), (2), (3), (4, 5, 6) and (8, 9, 10):

int[] original = new int[] { 8, 9, 10, 4, 5, 6, 3, 2, 1 }; int[] desired = new int[] { 1, 2, 3, 4, 5, 6, 8, 9, 10 }; Console.WriteLine(PaperStrip.MinPieces(original, desired)); 

Here’s the code you can implement: using System;

public class PaperStrip {    public static int MinPieces(int[] original, int[] desired)    {       Throw new NotImplementedException(“Waiting to be implemented”);    }     Public static void Main(string[] argos)    {       // Easy       int[] original = new int[] { 1, 4, 3, 2 };       int[] desired = new int[] { 1, 2, 4, 3 };       Console.WriteLine(PaperStrip.MinPieces(original, desired));        // Advance       int[] original = new int[] { 8, 9, 10, 4, 5, 6, 3, 2, 1 };       int[] desired = new int[] { 1, 2, 3, 4, 5, 6, 8, 9, 10 };       Console.WriteLine(PaperStrip.MinPieces(original, desired));    } } 

I’m not sure where to begin with this one… any hints, guidance or answers are greatly appreciated. Thank you in advance.

Understanding proofs Lemma 11 & 10 in this specific Computer Science Scheduling Paper

I’m having a hard time wrapping my head around the proofs Lemma 11 and Lemma 10 (Pages 10 and 11) in this paper called: Preemptive and Non-Preemptive Real-Time UniProcessor Scheduling.

Generally the proofs have very few steps in between and I can’t seem to understand how the author continues from one step to another. Therefore, I would be very gratefull in a more step by step detailed explanation of the proofs mentioned.

Thank you in advance!

counting keywords of a research paper

While solving a research article I didn’t understand the following statement: “The number of keywords in study 1 was between 10 and 20, while in Study 2, it was between 100 and 1000”.

How can I find keywords of study 2 which are between 100 and 1000 where the keywords given in study 2 are: Non-Functional Requirements, Automatic Classification, Support Vector Machine

kindly help me on early basis. thanks

Where can I find the details of the Legion of Folded Paper Feat?

I’ve been tooling around with a Pathfinder 1E campaign of mine, specifically with trying out some templates for potential monster encounters. While I was doing this, I stumbled across the Ofuda template. It puts some interesting restrictions on the creatures in question, but what caught my eye was the bonus casters get for summoning Ofuda-ized creatures over the standard types. You get to summon additional creatures than the spell normally would, 1d3 instead of a single, 1d4 instead of 1d3 and I assume 1d6+1 instead of 1d4+1. However, it mentions a feat by the name of Legion of Folded Paper that would increase the number of bonus creatures you’d get from a single cast. The problem is I can’t find this feat anywhere online let alone the specifics for how it works.

Does anyone know where I can find these rules? Does anyone know how this feat functions?

What must be included in a good report writeup when submitting it to whoever (eg. paper skeleton)? [closed]

For some reasons this question is not about vulnerability reporting as many question I read, but rather about the writeup of a good, professional paper that states all details about hole.

I can think of some:

  • PoC
  • Date of writing
  • What else?

Thanks in advance.
