Is there a way to solve for a system of multiple equations with multiple variables and variables on both sides in java Lets say im given three (or more) equations in an array list or array like so... 4A=1C 10A=2D 2B=2C+1D and im allowed to set one variable equal to 1 (lets say A) is there a java function or quick/simple aproach to get the values of each variable as whole numbers. (please help) |

How are you? Greetings to all of you. I have a task and that is to find the complexity of the counting algorithm sort line by line to finally find the T(n). The truth is that it has been quite a complicated subject for me, but I have been working on this so I would like to know if someone with knowledge of this can tell me if it is right or wrong. the pseudocode: ........................................cost..............repetitions for i = 1 to k do...............2.....................k+1 c[i] = 0 .......................... 1..................... k for j = 1 to n do ..............2 .....................n+1 c[A[j]] = … |

analyze the problem. walkthrough the code. I would like to charge for this solution $10 to Renewal Computer Services, if I may post here (kids & teens free). when -50 is reached, doesn't blow past the maxvalue+1U and cause a cpu-hogging forever loop, it doesn't actually reach -50 equivalent (UINTMAX-49). #include <cstdint> #define ufordown0(var,maxvalue,step) for(uint64_t var=maxvalue; var>maxvalue; var-=step) /* Example: ufordown0(i,200U,50U) { } */ |

I created a calculator only using the scripting commands in the video game Counter-Strike, bind (for input) echo (for output) and alias (for the logic). Bind is to connect keys to a command or string of specified commands, echo is to output text to the console, and alias is a command that allows you to create a new command out of a string of specified commands. Basically, I can do math without using math. This is pure connectionism, where there are no values, no logic operators and no measurements in the logic. It is purely making, breaking and using connections … |

Design a function named max that accepts two integer values as arguments and returns the value that is the greater of the two. For example, if 7 and 12 are passed as arguments to the function, the function should return 12. Use the function in a program that prompts the user to enter two integer values. The program should display the value that is the greater of the two. NEED HELP WITH >>>>>>>>>>>>>>>>> variable lists, IPO Chart, pseudocode, Flowchart |

You know the Pareto Principle? The 80/20 rule? That 80% of the work gets done by 20% of the people? Or 80% of the money belongs to 20% of the people? And so on? Well it is 'recursive' inasmuch as it can be applied again to the 20% first recognised. i.e. if 20% do 80% of the work then 20% of the 20% do 80% of they work THEY do. And so on. While I can get my head around recursion generally and can fully comprehend the standard recursive algorithm for calculating factorial - I'm not smart enough to put … |
