Linux Beginner-disk stretch reductionIn the process of using the system, this problem often occurs, due to the initial inability to estimate the required disk space, resulting in late disk space is not enough, so that the data is not stored, or later disk space is too large, resulting in a waste of resources. The problem of not estimating disk size before use can be solved by LVM.LVM when the partition of one or more disks is logically set, equivalent

Link: Ultraviolet A 11922-permutation Transformer Given a sequence, each operation extracts the range ~ B. Flip and put it at the end, and then output the sequence. Solution: stretch the tree. Set a flip for each node to indicate whether it is flipped or not. Each time a is rotated to the root, split, then flip B to the root, split, and put the mid to the end. #include Ultraviolet A 11922-permutation Transformer (

Simple operations to stretch a Splay tree The splay tree is a binary sorting tree. [I wrote it two months ago. Today I suddenly want to write a blog ...] Different from the general binary sorting tree, the tree is automatically balanced after each insert, query, and delete operation. (It is automatic, that is, there is a piece of code that mentions this node to the root node location) The adjustment of the stretch
