This code is to implement binary search. However, it did not work and return undefined. I don’t know why this went wrong, please help me! function binarySearch(arr, key) { let low = 0; let high = arr.length – 1; let mid while (low <= high) { mid = Math.floor((high + low) / 2); if (arr[mid]… Read More How can I debug this Javascript code for binary search

I want to use ggplot2 to plot a binary variable over time, such that whenever we observe the event (y = 1) for a given individual (id), there is a cross (or point) on the x-axis. Here is some data: access <- rbinom(n=500,size=1,prob=0.40) id = rep(1:10, each = 50) day_id = rep(1:50, 10) da =… Read More Plot crosses on time axis for a binary dependent variable

I was trying to convert characters to binary string form like "A" to "01000001". To implement this, I used the following C++ code #include <iostream> #include <string> #include <bitset> using namespace std; int main() { string message = "A"; string binaryString = ""; for (char character : message) { binaryString += bitset<8>(character).to_string(); } cout <<… Read More C++ Convert UTF-8 character to binary form

I have a binary matrix and I want to merge column an and b for example. If there is a 1 and a 0 then the output should be 1. 0 and 0 should stay 0, but 1 and 1 should also stay 1. a b c a 1 0 1 b 0 0 0… Read More R function to merge columns of matrix

I’m trying to read a old file of snow data from here, but I’m having a ton of trouble just opening a single file and getting data out. In the user guide, it says "Each monthly binary data file with the file extension ".NSIDC8" contains a flat, binary array of 16-bit signed, little-endian (LSB) integers,… Read More Reading "a flat, binary array of 16-bit signed, little-endian (LSB) integers" from file in python

I have some binary data im trying to save to a file using javascript. The backend sending the data is written in python. Here is the backend code for sending the binary data using flasks send_file: def exportSavedata(characterId): character = Characters.query.filter_by(id=characterId, user_id=current_user.id).first() savedata = character.savedata exportFolder = os.path.join(os.path.dirname(os.path.abspath(__file__)), ‘exportSavedata’) if not os.path.isdir(exportFolder): os.mkdir(exportFolder) filename =… Read More Saving Binary Data with javascript changes bytes

Im new to C, and used to python. But because of current situation in the world my primary computer was destroyed and all I left with is 12 years old laptop. Python would not work really good there. My goal is to create encryption algorithm. Currently its fairly simple, but I will upgrade it later… Read More Read binary file chunk by chunk in C
