The apple client receives the data from the background and needs to convert it into an object before it can be used. Some beginners or lazy people may directly use the results put back in the background without object conversion. Even no matter what type of data is processed according to string, it will be converted to the types defined by inte ...

preface (7.3, 3 lessons short, do your best!) This article is the learning notes for the eighth lecture of the algorithm class. 3-2 section 2 of Chapter V: hash table and bloom filter (as usual, the shortest learning time is still challenged this time, and it is expected to be less than 3 times the time) (the difficulty of this course ...

Question 1: the next larger element I The next larger element of the number x in nums1 refers to the first element larger than x to the right of the corresponding position of X in nums2. Give you two arrays nums1 and nums2 without duplicate elements. The subscript counts from 0, where nums1 is a subset of nums2. For each 0 < = I < nums1 L ...

preface It's too difficult ~ but the winter camp talks about this thing. Open the pit in advance. Pre cheese Define #define ls tr[x].ch[0] #define rs tr[x].ch[1] struct Tree{int ch[2],val,fa,rev,xv;}tr[MAXN]; LCT? How does LCT surpass the general tree section and balance tree to achieve the effect of maintaining a forest? LCT has some properti ...

Basic introduction to merging and sorting Merge sort is a sort method based on the idea of merging. The algorithm adopts the classical divide and conquer strategy Divide and conquer divides the problem into some small problems and then solves them recursively, while the conquer stage "fixes" the answers obtained in different stages, ...
