Time Complexity: O(n) In this article we will see how to find out all such triplets from a given list of numbers. Finally, it returns the results list. A list of the distinct element is given; we need to find the triplets in the list whose sum is zero. If you have any more approaches or you find an error/bug in the above solutions, please comment down below. In the above code, first, we sort the array in ascending order and traverse the array from start to end. You can also set list elements in this way. Do the subject and object have to agree in number? Every time we make a combination of 3 elements and check if they sums up to k or not. at Facebook.
