Sum Of All Fears


  • Given a list of numbers and a number K, return whether any two numbers from the list add up to K.
  • I have built two variations, one that finds all pairs and on that just determines if there is a pair of numbers that add up to K.
  • (you can view both variations on the code page)

  • This challenge or a slight variation has been used by technology companies such as
  • Amazon and Google and was also featured as a Daily Coding Problem in dev.to.

  • This project was created using Bootstrap 4.5, HTML5, CSS3, and JavaScript.
  • All logic & JavaScript DOM changes were custom coded for this project.
