Sum of nodes in binary tree
Did you know?
WebYou are given a binary tree having 'N' nodes. Each node of the tree has an integer value. Your task is to find the maximum possible sum of a simple path between any two nodes (possibly same) of the given tree. A simple path is a path between any two nodes of a tree, such that no edge in the path is repeated twice. Sum of a simple path is ... Web$\begingroup$ Even simpler: A binary tree with depth 0 has 1 node (the root), not 0 nodes. But check your source's definitions. If they define depth as the number of nodes on the longest root-to-leaf path, instead of the (more standard) number of edges on the longest root-to-leaf path, then their statement is correct. $\endgroup$ –
WebYour task is to find the sum of the subarray from index “L” to “R” (both inclusive) in the infinite array “B” for each query. The value of the sum can be very large, return the answer as modulus 10^9+7. The first line of input contains a single integer T, representing the number of test cases or queries to be run. WebGiven the rootnode of a binary search tree and two integers lowand high, return the sum of values of all nodes with a value in the inclusiverange [low, high]. Example 1: Input:root = [10,5,15,3,7,null,18], low = 7, high = 15 Output:32 Explanation:Nodes 7, 10, and 15 are in the range [7, 15]. 7 + 10 + 15 = 32. Example 2:
