This section describes how to use interfaces in Unreal Engine 4 to use C ++ and blueprints. This tutorial is based on UE4 Wiki. You should be familiar with using interfaces directly in C ++. Simply define the basic classes with virtual functions

Hdoj1874 (priority queue + Dijkstra), hdoj1874dijkstra Hdoj1874 Analysis:At first glance, the question is to find the shortest path. This question uses the Dijkstra + priority queue. The Dijkstra algorithm expands a node with the shortest distance

C/C ++ reads an integer with an indefinite number in a row and an integer I think it is quite simple for everyone to encounter this problem at the beginning. However, it may be a bit difficult to implement. After all, for a mature and widely used

Hdu 4000 Fruit Ninja (tree array) The general idea is to give a string of 1 to n (set as array a), and find that a [x] is satisfied. Directly finding the number of such orders is not optimal. We can convert it to a [x]. Use the left array to record
