1038 Recover the Smallest Number (30 分) Given a collection of number segments, you are supposed to recover the smallest number from them. For example, given { 32, 321, 3214, 0229, 87 }, we can recover many numbers such like 32-321-3214-0229-87 or 022
Given a non-empty tree with root R, and with weight Wi assigned to each tree node Ti. The weight of a path from Rto L is defined to be the sum of the weights of all the nodes along the path from R to any leaf node L. Now given any weighted tree
