object.prototype points to null (end);In the article structure by the way with two methods related to the prototype chain .... Welcome to use1.hasOwnProperty a property or object that determines whether an object has a name, This method cannot check whether the object has that property in its prototype chain, and the property must be a member of the object itself.Returns true if the property or method is defined in the Object's own definition rather than in the prototype chain; The format is as

software to set up, push the camera's live signal data to the streaming media server for publishing. This way you need to know some of the settings and basics of live push streaming. You can select the 800li Live encoder software, or you can choose adobe Flash Media live Encoder to encode the push stream.

Problem Description:AC Source:The key is that the data is very large, can not be strong, need to use skills, where the use of scientific methods, so that n^n=a*10^n, take the logarithm to N*log10 (N) =log10 (a) +n, so that x = log10 (a) +n and N = Int (x) [Rounding, of course, according to the number of According to the scope, in order to avoid overflow, this is used is a long long to take the whole], then A = 10^ (X-int (x)), and finally brought into x= n*log10 (N), the value of a rounding is t
Title Description:AC Source:This study greedy algorithm, problem-solving ideas: the principle of greed is to make the largest space left, preference for BI and AI difference between the largest, as to why? Here with only 2 equipment for example, (A1,B1) and (A2,B2), assuming that the first transport A1, the moment of transport, the actual space to occupy should be a1+b2, then in order to ensure that the largest space left, there should be a1+b2#include "iostream" #include "algorithm" using names
