the game scores, you can set such as 1 times to guess the 10 points, 2 times to guess the 9 points, and so on. Then divide the player's total score by the number of rounds they play, which is the average score. use a file to store a lot of words, like a dictionary, and then randomly choose from it: so you can play alone, do not need someone to give you a quiz. Your program randomly selects a word from the file, disrupts it, and then you can guess for yourself. Here is an example of a dict

Read someone else's blog and jot it downLet's take a look at the following code1 var a=1,b=2,c=3; 2 3 (function() {4 var a=b=1; 5 })(); 6 7 Console.log (a); 8 Console.log (b);This is a well-known closure, yes, a very important use of closures is that variables can not be accessed externally, will not pollute the external variables , so you would think that the results of 7,8 rows are 1 2? Otherwise, 7, 8 rows of the correct result is 1, 1. Why is that? I also think t

Idea: First find the maximum value in the array i[] to be sorted, create an empty array with the size (max. +1) kk[], and then traverse the value N in the array i[] to be sorted, whose value n corresponds to the nth element in the array kk[] plus 1. Finally, the values of the array kk[] are assigned back to the value i[].Evaluation: This algorithm has a time complexity of O (3n)The code is implemented as follows:Int[] I ={2,6,9,8,5,6};int temp = i[0];for (int k = 1; k {if (I[k] > Temp) {temp = I

CDP is short for Cisco Discovery Protocol, a data link layer Protocol. Through this Protocol, our network administrator can obtain information about devices that run the CDP Protocol adjacent to each other. CDP protocol version: CDP protocol is divided into two versions: CDPv1 and CDPv2. cisco router 12.0 (3) T or later IOS versions support CDPv2. CDPv1 is enabled by default in IOS 10.3 to 12.0 (3) T versions. When a cisco device is started, the CD

Before, in the absence of an application that found the VS tool Python Project search paths, for example: If the project's file directory is as follows:maintest/maintest.py you want to use the common/tools.py file, you have to add such code to the code in maintest.py:Import SYS Import OS from Import = Os.path.join (Os.path.dirname (Os.path.dirname (__file__"\common " # Add the directory where tools resides to path Import Tools Print Path Print TOOLS.AIn this case, the code is not concise enoug

: A platform-dependent backend generates low-level intermediate code representations from Hir (intermediate representation), which is preceded by other optimizations on hir, such as null-value check elimination, range-checking elimination, etc. So that hir can achieve a more efficient code representation. Phase three: Use the linear scan algorithm (Linear Scan register Allocation) on the platform-related backend to allocate registers on the Lir, and do a peek optimization (peephole) optimiza

Because of the rapid development of mobile internet industry, the advertising platform has also appeared in the CPM, CPC, CPA fees, but these effects are n

. And RN is now divided into two sets of code, one is the Android is iOS. But the difference is not big. The UI written by HM has tried, it's a little bit uncomfortable, and it's very difficult to write the layout of the special dot. In this place RN has a great advantage.In terms of the cost of learning, I prefer RN, because the JS code of RN is react.js, but the use of JSX standards. The current contact of the two framework, I still prefer RN, although the development of HM is quite high effic
