The Road To Mastery From Ruby intermediate to Master... RSS Blog Archives ’Pair With Sum’ Problem | Comments Recently, I Have been researching common coding interview-problems and I’ve discovered that most of the major tech companies like Google or facebook have overlapping problem lists. One of these problems is called Pair With Sum and it states the following Find a pair of elements from an array whose sum equals a given number . This request is a bit ambiguous - so let’s start out by listing all the assumptions that we are making before we begin working on a solution: The array contains only integers The array can have duplicates Return a boolean that indicates if the list has such a pair We will start with an ordered (ascending order) list example Brute force Lets code the most naive solution. Basically, try every pair possible and see if their sum is equal to the given number. It would look like this in Ruby 1 2 3 4 5 6 7 8 9 10 def has_pair_with_sum_brute_force ( input , sum ) 0 |
