CPP 1373 Easy as A + B (Bubble Sorting)
Question:
Easy as A + BTime Limit: 1000 MS Memory Limit: 32768 KDescription: These days, I am thinking about a question, how can I get a problem as easy as A + B? It is fairly difficulty to do such a thing. of course, I got it after refreshing waking nights. give you some integers, your task is to sort these number ascending. you shoshould know how easy the problem is now! Good luck!

Title Link: Http://codeforces.com/contest/931/problem/DThe main topic: give you a tree, each node will grow apples, and then every second, apple roll down one. Two of the two will counteract the apples. Ask how many apples can be received at the root node at the end.Problem-solving ideas: Yesterday is I want to complicate, in fact, the statistics of each layer of the number of apples, if the odd answer +1. Because eventually these apples will tumble and converge to the root node, so in the rolli

The function of calling JScript in C + + is simple, Windows provides a MSScript.ocx control that allows you to manipulate JScript directly: Execute a section of JScript script, or call a specified function. I wrote a simple example:
