Why is it showing Run-time error in 3Sum problem on LeetCode? Approach: For each point calculate it's distance to every other points. For instance, (19,11,7) is a valid decreasing triplet because these numbers come from different sub-lists and are in decreasing, natural order (19 comes before 11 which comes before 7 in the master list). By using our site, you Below is the implementation of the above approach: Time Complexity: O(N)Auxiliary Space: O(1). Guide to Triplets: How to Play and Count Triplets in Music. Approach1: Simple Approach Algorithm We start with an integer array named Arr [] that has been filled with random numbers. For example, a naive O (n^3) solution can be made faster by looping over elements and counting how many elements to their left are less, and how many to their right are higher, then multiplying these two counts, and adding it to a sum. Is not listing papers published in predatory journals considered dishonest? For a pair (p, q) the problem now reduces to finding the number of elements r in the sorted array such that r <= X/(p*q). Input: X = {1, 2, 3, 4}, Y = {5, 6, 7, 8}, Z = {9, 10, 11, 12} Output: 4 Space Complexity: O(N), as a map is used. All Contest and Events .

To clarify with a counter-example: (15, 9, 8) would not be a decreasing triplet because the 9 is coming from an earlier sublist than 15. Contribute your expertise and make a difference in the GeeksforGeeks portal. Efficient Approach: The above approach can also be optimized by the observation that for any given index i, the number of triplets having arr[i] as their middle element will be the count of integers smaller than arr[i] in the range [1, i 1] * count of integers larger that arr[i] in the range [i + 1, N].
