We аll knоw аnd lоve the clаssic rubber ducks (rubber duck debugging, anyоne?). We’ve put them in the river! But this is a special river. The river makes it so that whenever a rubber duck bumps into another, the larger rubber duck absorbs the smaller but keeps its original value! You are given a vector ducks of integers representing the rubber ducks in a row. The indices of the ducks in the vector represent their position in the river. For each duck, the absolute value represents its size and its sign represents its directions (positive means right, negative means left). Each duck is moving at the same speed. No duck will have a value of 0. We want to know which ducks are left standing after all bumps occur. As noted above, if two rubber ducks bump, the smaller will be absorbed by the larger one (but will keep its original value). If both ducks are the same size, their bump will make them disappear! (Magical rivers amirite?) Rubber ducks moving in the same direction will never meet. The order of ducks should be preserved. That is, if duck1 is before duck2 in the input vector and both ducks survive, then duck1 should be before duck2 in the output vector. Constraints: Each duck will be less than 0 or greater than 0. A duck will never have a value of 0 Examples: Input: [3, 10, -2]Output: [3, 10]Explanation: The zeroth duck and the first duck are moving in the same direction. The first duck and the second duck are moving in opposite directions (note how the signs are different). The first duck and the second duck will meet and since the absolute value of the first duck is larger than the second one, the first duck will absorb the second one. Input [-9, 2]Output: [-9, 2]Explanation: Since the zeroth duck is moving to the left and the first duck is moving to the right, no one will bump! Input: [9, -9]Output: []Explanation: These ducks bumped and since their absolute values are equal, they disappeared! Input: [7, 3, -12]Output: [-12]Explanation: The zeroth duck and the first duck are moving in the same direction. The second duck is moving in the opposite direction. The magnitude of the second duck is greater than the zeroth and the first duck. So, the second duck will bump with the first duck and absorb it. It will then bump into the zeroth duck and absorb it too!

Prоfessоr Amаn hаs spent yeаrs researching the beauty оf binary trees, specializing in the art of adding up node values. With each node containing a number, and the potential to contain a left and right subtree, the total value of the tree can reach great heights! Despite this, he is quite picky about which nodes to add to the precious total... Professor Aman only adds the values of the outermost nodes, which are the left-most and right-most nodes at each level. As his handy dandy research assistant, you must solve the following assignment: Given the root of a binary tree, write a function in C++ that returns the sum of the values of the outermost nodes of each level in the tree. If there is a single node in a level, you should only include its value once. If the tree is empty, return 0. Start off with this function header: int sumOutermostNodes(TreeNode* root) { // your code here} Input Constraints: All node values are >= 1. All node values are unique. Example Input: Example Output: 54 -> add 2 + (5 + 7) + (1 + 9) + (14 + 6) + 10 You can test your code at these locations: https://www.onlinegdb.com/ or https://cpp.sh/
