问题 This code asks the user for a triangle height and a letter. import java.util.*; public class triangle { public static void main(String [] args) { Scanner kb = new Scanner(System.in); int size = 0; Character c; System.out.println("Enter height of the triangle : "); size = kb.nextInt(); System.out.println("Which character you want to use : "); c = kb.next().charAt(0); int i, j, k; for (i = 0; i < size + 1; i++) { for (j = size; j > i; j--) { System.out.print(" "); } for (k = 0; k < (2 * i - 1);

问题 Description of the file: The STL file consists of solid <solid_name> facet normal n1 n2 n3 (the triangles normal vector) outerloop (one of the markers I want to read) v1 x1 y1 z1 v2 x2 y2 z2 (three vertex of the triangle/facet) v3 x3 y3 z3 endloop end facet endsolid The idea is to read the information in each line. First, I'm trying !to read the first line:solid program Leitura !use, intrinsic :: trim implicit none integer ilo, ierror, ihi, ios, iunit, num_text, len_blanck, len_word, len_text

问题 Below is a couple of rows of some test data I am using. I am wanting to count the frequency of all the characters in the ICD10Code column which are separated by columns. From the segment of code below, I used group_by because every "PatientId" value had duplicates in that column but had unique values in other columns. How can I go about counting the frequency of all character values? PatientId ReferralSource NextAppt Age InsuranceName ICD10Code 1584 St Francis Y 34 SLIDING FEE SCHEDULE M5136,

问题 I have a list of item ids as below: ids <- c("12_a","23_b") Considering these item ids, I would like to generate a character variable as below for three groups (G1, G2, and G3). #for the first item Equal = (G1,12_a, Slope[0]), (G2,12_a, Slope[0]), (G3,12_a, Slope[0]); Equal = (G1,12_a, Slope[1]), (G2,12_a, Slope[1]), (G3,12_a, Slope[1]); Equal = (G1,12_a, Slope[2]), (G2,12_a, Slope[2]), (G3,12_a, Slope[2]); Equal = (G1,12_a, Intercept[0]), (G2,12_a, Intercept[0]), (G3,12_a, Intercept[0]);

问题 I've looked around and can't seem to find a decent way to solve this issue. I have a column that has rows of names. I'd like to sort each row alphabetically so that I can later identify rows that have the same names just in different orders. The data looks like this: names <- c("John D., Josh C., Karl H.", "John D., Bob S., Tim H.", "Amy A., Art U., Wes T.", "Josh C., John D., Karl H.") var1 <- rnorm(n = length(names), mean = 0, sd = 2) var2 <- rnorm(n = length(names), mean = 20, sd = 5) df <

问题 I would like to create a type to contain an array of strings in Fortran without explicitly assigning lengths so I can return it from a function. The following is my type: type returnArr Character (*), dimension(4) :: array end type returnArr The following is the function's signature: type(returnArr) FUNCTION process(arr, mean, stdDev) result(j) The following is where I try set the result: j%array(1)= "Test" But all I get is the following error: Error: Character length of component ‘array’

问题 I want to print n Greek characters in Java starting from alpha (whitch has the "\u03B1" code).This is what I had in mind: String T = ""; for(int i = 0,aux = 0;i<n;i++) { aux = '\u03B1' + i; T +=Character.toString((char)aux); } System.out.println(T); But it prints n question marks instead. Let's say n=3,on the output i get "???". I thought that maybe my method is wrong but then again if I try something like this: System.out.println("\u03B1\u03B2\u03B3"); I get the same output:"???" Why do I
