Given a binary tree and an integer K. Find the number of paths in the tree which have their sum equal to K. A path may start from any node and end at any node in the downward direction. Time Complexity: O(n).Auxiliary Space: O(n), The extra space is used in map. Please refresh the page or try after some time. Find count of triplets with sum smaller than given sum value. The triplets satisfying are index , , , . This article is being improved by another user right now. Pointer to the last node can be found only once in the beginning. All three numbers are equal to 0. The time complexity of this solution is O(n). Once we find the starting point, we can simply traverse the given map to print itinerary in order. You need to find the number of good triplets. Return the number of good triplets. Prepare for your technical interviews by solving questions that are asked in interviews of various companies. The task is to find the number of triples (i, j, k) , where i, j, k are indices and (1 <= i < j < k <= N), such that in the set {,,} at least one of the numbers can be written as the sum of the other two.Examples: This is a counting problem.
