This does feel a lot like a school project/task rather than anything meaningful. There are libraries built into Ruby that you can use for high performance Prime calculations puts “Enter the maximum number of the range in which to find the prime numbers: ” last = gets.chomp.to_i prime = [2] all_numbers = (2..last).to_a print “We … Read more
I read you say that your variable is changing, but where? Two things: you’ve got to change the variable you’re checking AND you have to change that condition test, that while loop condition is True when the variable var[5] is different than ‘left’ or different that ‘right’ (if it’s “left”, then it’s different than ‘right’ … Read more
I just write this function for him. Please don’t justify people from how he write the code. Maybe it’s easy to say “Hey! Do you know javascript?”. It’s better if you leave some answer or stay quite. His code is valid javascript. https://gist.github.com/ethaizone/b7d3a833dcdeb80234dde516649ac06d#file-buildmultidimentionarray2-js solved Looping Object javascript
You can use char[] to read input. I have modified your program as follows; int main() { int sum=0; int pos=0; int neg=0; double ave=0; char arr[100] = {‘\0’,}; std::cout << “Enter an integer, the input ends if it is 0: ” ; gets(arr); int index = 0; char ch[1]; bool negativeNumber = false; while(true) … Read more
I don’t know what initial values b, x, w and y got so I just initialized them somehow .. But I think you want something like this: public class HelloWorld{ public static void main(String []args){ int z = 26; int b = 0; int x = 1; int w = 2; int y = 1; … Read more
In your second code block you are first checking if the first character is the same as the last. If it isn’t, return false. Else, return true. So this isn’t going to be a valid palindrome check. It only checks if the first and last letters are the same or not and ignores the letters … Read more
I think you are a beginner. So i will help you to get stand. Try this code. class InputTest { public static void main(String[] args) { System.out.print(“Enter size of array: “); Scanner scanner = new Scanner(System.in); int numberOfArray = scanner.nextInt(); Integer[] input = new Integer[numberOfArray]; for (int i = 0; i < numberOfArray; i++) { … Read more
Ok, as now we have seen your attempt, I would suggest you to grasp some concepts of Python and get an understanding of Python’s libraries and builtins, esp, in this case, you need to understand zip and all. You also need to understand about iterable and List Comprehension. Zip is a wonderful function, and comes … Read more
First lets make so data to experiment with set.seed(100) example <- matrix(runif(47*30), nrow = 47) example[sample(length(example), 250)] <- NA Now we can calculate our means. The apply function samples a random value from each row (!is.na excludes NA values), mean gets the mean, and replicate repeats this 10000 times. exmeans <- replicate(10000, mean(apply(example, 1, function(x) … Read more
If you want to have a random number of arrays you have to store them in a resizable container like a vector, containing the arrays with the six elements. Resize this vector with this random number and then iterate through it and add random numbers #include <array> #include <random> namespace { constexpr auto NumberOfArrayElements = … Read more
Use the json package and load the json. Assuming it is a string in memory (as opposed to a .json file): jsonstring = “”” [ { “issuer_ca_id”: 16418, “issuer_name”: “C=US, O=Let’s Encrypt, CN=Let’s Encrypt Authority X3”, “name_value”: “sub.test.com”, “min_cert_id”: 325717795, “min_entry_timestamp”: “2018-02-08T16:47:39.089”, “not_before”: “2018-02-08T15:47:39” }, { “issuer_ca_id”:9324, “issuer_name”:”C=US, O=Amazon, OU=Server CA 1B, CN=Amazon”, “name_value”:”marketplace.test.com”, “min_cert_id”:921763659, … Read more
(double…values) means the method takes one or more parameters. You can call the method with different number of parameters. They are threated as an array. findMax(23.0, 13.0); // values array contains 2 double value findMax(12.0,13.0,17.0) // values array contains 3 double value for(double v : values) means the for loop iterates on every element in … Read more
If you want to cycle the list elements, you can use itertools.cycle. We can call next twice on each iteration to get two numbers at a time from the iterator. from itertools import cycle a = cycle([0,1,2,3,4,5,6]) for _ in range(10): print(f”{next(a)} – {next(a)}”) Output: 0 – 1 2 – 3 4 – 5 6 … Read more
Let’s look at the the two loops individually. The outer loop starts with i=1, and increments it by k in each iteration, until it’s greater than n. In other words it can run n/k times, or, to be accurate, floor(n/k) times, since a loop can’t run a non-whole number of times. The inner loop is … Read more
I have taken the first permutation algorithm I found in wikipedia and implemented it in Delphi (2009); I hope that is what you are looking for: type TIntegerArray = array of Integer; procedure Permutation(K: Integer; var A: TIntegerArray); var I, J: Integer; Tmp: Integer; begin for I:= 2 to Length(A) do begin J:= K mod … Read more
