logic

问题 So im trying to add 1+2+3... and so on...without using brute force. Y=∑_1^100▒X_i, the numbers Xi are stored in consecutive memory locations starting at location 100. I am using the IAS instruction set: I just cant seem to get this done. I dont even know where to begin, no real loops or if statements 回答1: You have 4 different possible approaches, that I will write in x86 since my knowledge of IAS is very limited, but you can apply the same logic 1/ Brute force xor eax, eax mov ecx, 100

问题 I am a beginner in Java programming and I have an assignment where I need to get posts from the Twitter API and implement a logic using Eclipse Java Photon. I managed to get the Twitter posts using Twitter 4j API but I am stuck of how to calculate the average words per tweet for the last 5 tweets. Can anyone help me understand how to do this please ? 回答1: You can get tweet contents and then split them into words. After that you can get average word count by counting the words and dividing it

问题 I should preface this by saying this is a homework problem that I am having issues with, and Im not sure if that sort of thing is allowed around here, but I dont know where else to turn to. This is the question I've been asked: In the sample code for this question, you can see a Fibonacci predicate fibSimple/2 which calculates the Fibonacci of X, a natural number. The problem with the naive recursive solution, is that you end up recalculating the same recursive case several times. See here

问题 We use NFA to model BadPrefixes for the safety property.I want to understand for a given Safety property , how to model the NFA. The following images are for reference. For instance, for safety property P2 ,Can someone explain how to know how many states are required(solution has 4) and which logic to use on the edges, how in Fig.,3 and Fig.4 , the edges are selected to satisfy the badprefixes P1 and P2.Thanks. 回答1: We have several definitions and notations here, let's go through these first:

问题 OK, I know it's a vague question, but I seem to be stuck with logic here...I want to create flow charts of the input programs. I hav been thinking about it since two days and can't get a best general approach...So i look desperately at you guyz to help me here....may be there is something small I am missing.... I have an xml file which contains the info about the given java program and looks like this: <Method modifier="publicstatic" type="void" name="main" > <FormalParameter modifier="" type

问题 Every day, we receive huge files from various vendors in different formats (CSV, XML, custom) which we need to upload into a database for further processing. The problem is that these vendors will send the full dump of their data and not just the updates. We have some applications where we need only send the updates (that is, the changed records only). What we do currently is to load the data into a staging table and then compare it against previous data. This is painfully slow as the data

问题 I have the need to create a plugin system that will have dependency support and I'm not sure the best way to account for dependencies. The plugins will all be subclassed from a base class, each with its own execute() method. In each plugin class, I'd planned to create a dependencies attribute as a list of all the other plugins it depends on. When loading the plugins, I would import all of them and put them in a list and sort them based on the dependencies. Once they are all in the correct
