NOTE: If there is a tie, then compare with segment's length and return segment which has maximum length. . Given a binary tree with a value associated with each node, we need to choose a subset of these nodes such that sum of chosen nodes is maximum under a constraint that no two chosen node in subset should be directly connected that is, if we have taken a node in our sum then we can’t take its any children or parents in consideration and vice versa. An efficient approach will be to find the divisors in O (sqrt n). Largest Sum Contiguous Subarray using Dynamic Programming: For each index i, DP [i] stores the maximum possible Largest Sum Contiguous Subarray ending at index i, and therefore we can calculate DP [i] using the mentioned state transition: DP [i] = max (DP [i-1] + arr [i] , arr [i] ) Below is the implementation: C++. So, the minimum spanning tree formed will be having (9 – 1) = 8 edges. Tree. Given a binary tree with a value associated. Output : 7 Explanation : 3rd smallest element in the given array is 7.
