The reason is that you have a lot of duplicated pairs. Now it depends whether your interviewer will accept this answer. This is what I meant: it’s easy to underestimate the difficulty level of the puzzles, only to learn that you did a careless mistake again. Here is what I mean:įor (j, element_2) in enumerate(l):įail! It throws an exception: “AttributeError: ‘list’ object has no attribute ‘add’” The straightforward solution is to use two nested for loops and check for each combination of elements whether their sum is equal to integer x. Question 5: Find pairs of integers in a list so that their sum is equal to the integer x. *FREE* Question 1: Get the missing number from an integer list 1-100. You will simply become a better Python coder on autopilot.
