euler tour technique造句

To address this problem, we make use of an algorithm called prefix sum by using the Euler tour technique.
Their data structure uses an Euler tour technique to transform the input tree into a sequence and then finds range minima in the resulting sequence.
With the Euler tour technique, a tree could be represented in a flat style, and thus prefix sum could be applied to an arbitrary tree in this format.
The sequence resulting from this transformation has a special form ( adjacent numbers, representing heights of adjacent nodes in the tree, differ by ? ) which they take advantage of in their data structure; to solve the range minimization problem for sequences that do not have this special form, they use Cartesian trees to transform the range minimization problem into a lowest common ancestor problem, and then apply the Euler tour technique to transform the problem again into one of range minimization for sequences with this special form.
