Sort algorithm heap sort
1. Heap sequencing (taking the big top heap as an example) (1) heap sorting is a time complexity O (nlog2n) (the number of times to initialize the heap n (the number of times to initialize the heap for several sorts) × The process of building heap is log2n (the process of finding the largest nuUTF-8...

LRU algorithm (detailed, java code implementation)
LRU algorithm as a common interview problem, it is time to learn in depth 1. LRU 1.1. Principle The core idea of LRU (Least recently used) algorithm is that "if the data has been accessed recently, the probability of being accessed in the future will be higher". 1.2. Implementation The most comUTF-8...
