function

问题 I'm trying to figure out how to implement a non-recursive algorithm for the Hanoi Towers problem in function hanoi_2 below, but I have no idea how to continue... It throws an error: "can't pop from empty list" . It works somehow when I input an odd number, however, when the third turn passes things go wrong. When an even number is input as the number of discs the program doesn't even start. What is wrong? from turtle import * from tkinter import * # used for the dialog box from tkinter

问题 i am currently confused as to how i can pass an array of strings to a function. I have created a one-dimensional array. The method that i have done works but it seems redundant and i think there is a better way of doing this yet i am unsure how. I am trying to find a way where i can pass all 4 elements to the function at one time. Here is the sample of my code. #include <stdio.h> #include <string.h> #include <ctype.h> void sort(char *,char *,char *, char *);//Function prototype int main() {

问题 I have a data frame which specifies "bridge games" (every row is one independent game), see a minimal example with 4 games below: start <- list(c("10","15","5"), c("5") ,c("11","6"),c("6","11")) end <- list(c("7","17","11"), c("10"), c("8","12"),c("8","12")) ascending <- c("+","-","+","-") position <- c(11,6,9,8) desired_output <- c(5,5,"disqualified",3) bridge_game <- data.frame(start = I(start), end = I(end), ascending = ascending, position = position, desired_output = desired_output)

问题 I'm having an issue compiling the beginnings of a basic password protected file program, I'm getting the above error on line 11, (int login(username,password)). Not sure what's going on here, so it'd be nice if someone could shed some light on the situation. #include <iostream> #include <conio.h> #include <string> using namespace std; int i,passcount,asterisks; char replace, value, newchar; string username,password,storedUsername,storedPassword; int login(username,password); { if (username=

问题 Suppose I have a list of objects called bb . I want to pick each unique pair of elements in bb and use them in some kind of function (called convolve ) as shown below: ## Below `bb` elements: `bma1` & `bma2` are used in the function: con <- convolve(dens1= bb$bma1$dposterior, dens2= function(x){bb$bma2$dposterior(-x)}, cdf1= bb$bma1$pposterior, cdf2= function(x){1 - bb$bma2$pposterior(-x)}) con$quantile(c(0.025, 0.975)) Question: bb can have any number of elements but convolve() accepts only
