WebMar 18, 2024 · The common node sequence from the root to the leaf nodes is the log template. Based on the above process, Prefix-Graph shows excellent accuracy with various datasets. When dealing with datasets with many templates and long log messages, the prefix tree traversal and merging steps in the algorithm will bring a certain amount of time … WebThe pvrt[] array represents the preorder traversal so that the first element would be the root of the special binary tree. We make the root node and insert the value in it. We traverse the pvrt[] array. If the indexed node is not a leaf node, push its value into the stack. We check the left of the stack’s top.
