This question already has an answer here: Finding contiguous ranges in arrays 8 answers Longest Consecutive Sequence in an Unsorted Array [duplicate] 8 answers I was asked this in an interview. Given a list of integers, How can we find the biggest interval that has all its members in the given list? E.g. given list 1,3,5,7,4,6,10 then answer would be [3, 7]. Because it has all the elements between 3 and 7. I tried to answer but I wasn't convincing. The approach I took was to first sort the list and then check it for the biggest interval. But I was asked to do so in O(n) . I know a solution

I recently completed a university course which featured Haskell and Agda (a dependent typed functional programming language), and was wondering if it was possible to replace lambda calculus in these with combinatory logic. With Haskell this seems possible using the S and K combinators, thus making it point-free. I was wondering what the equivalent was for Agda. I.e., can one make a dependently typed functional programming language equivalent to Agda without using any variables? Also, is it possible to somehow replace quantification with combinators? I don't know if this is a coincidence but

I have a Phone interview coming up next with with a company which works in financial software industry. The interview is mainly going to be in C++ and problem solving and logic. Please tell me the method of preparation for this interview. I have started skimming through Thinking in C++ and brushing up the concepts. Is there any other way I can prepare?? Please help. Edit: Thank you all everyone for the advice. I just want to add that I am currently fresh out of grad school and have no previous experience. So Can you suggest some type of questions that will be asked to new grads?? Make sure you

Each point in the matrix represents a cell, living or dead. I have to count how many ALIVE neighbors each cell has. I have a function that does the job, but it checks for cells outside its boundary.I don't know how I can simultaneously check for neighbors and keep track of edges without doing a massive amount of if-else statements. void Neighbours(int rows, int cols, cell world[rows][cols], int neighbors[rows][cols]) { //Loop through each cell in the matrix. for(int rCell = 0; rCell < rows; rCell++){ for(int cCell = 0; cCell < cols; cCell++) { //Reset neighbor count for each cell. neighbors

I am creating application where I upload, download files in my azure storage account through java services. When I upload files with name having no space in their name(example : "image.png"), program returned me token successfully. But when I try to get token while uploading or downloading for file names having spaces in between them like "new image.png" , it gives me error at particular line. My code is : CloudFile cloudFile = directory.getFileReference(fileNameWithExtension); String tokenKey = testFileSAS(share, cloudFile); System.out.println(cloudFile.toString()); cloudFile.downloadToFile

This question already has an answer here: Using wire or reg with input or output in Verilog 5 answers I'm confused about reg and wire when I was doing my homework. I could not understand differences between reg and wire exactly. Can you explain shortly? Also, I wonder that what will happen when I use output q instead of output reg q ? In simulation , a Verilog wire behaves like a piece of metal, a track, a wire, whilst a Verilog reg is a variable, it is storage*. The difference between them in simulation can be illustrated by showing what happens if I assign to them from more than one place.

I'm trying to use monthly stock data from yahoo to analyze patterns. For some reason, the monthly returns the program is spitting out in a dataframe for a particular stock (ATVI) do not match the returns from the actual yahoo site. I compared monthly returns for the 2015 period and included columns for average increases and decreases as well as the # of occurrences of each. Yahoo link: https://finance.yahoo.com/q/hp?s=ATVI&a=00&b=1&c=2015&d=11&e=31&f=2015&g=m My code: from datetime import datetime from pandas_datareader import data, wb import pandas_datareader.data as web import pandas as pd

I am trying to search for multiple items in a cell. If any of the terms I am looking for is present, I want cell D to display "Laptop", otherwise, display "Desktop". I can get the following to work, with just one term to search for: =IFERROR(IF(SEARCH("blah",A2),"Laptop",""),"Desktop") But I want to search for the presence of blah, blah2, and blah3. I don't know how to get Excel to search for any of the following terms. (Not all of them mind you, just any of the following. I did see that there is an or option for the logic. =OR(first condition, second condition, …, etc.) I am not sure how to

I wanted to subset data frame project I was working with, using a logical. I am getting a paradoxical result. The part of the logical preceding the ROLL.NO. argument is irrelevant to the question. Sorry, I could not give a reproducible example. Do let me know how can I make this question reproducible without having to show the entire 393 entries of the relevant columns in my data frame. D14 and DC31 are simple integer values, with some values being NA . culprits<-project$ROLL.NO.[(project$DC31==1&project$D14==2)|(project$DC31==2&project$D14==1)&!is.na(project$DC31)&!is.na(project$D14)]

I am attempting to create a maze program in Prolog, whereby the aim is to find a route from the start of the maze to a point in the centre of the maze called m. The maze consists of squares which are connected using one of four colours: Blue, Green, Purple or Orange. The route from start to the centre follows a repeating pattern of the four colours. I have created the following code: link2(A, Colour, B) :- link(A, Colour, B). link2(A, Colour, B) :- link(B, Colour, A). changecolour(blue,green). changecolour(green,purple). changecolour(purple,orange). changecolour(orange,blue). route(A, Colour1,
