问题 I've been trying to fit a function to some data for a while using scipy.optimize.curve_fit: from __future__ import (print_function, division, unicode_literals, absolute_import) import numpy as np from scipy.optimize import curve_fit import matplotlib.pyplot as mpl x = np.array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29]) y = np.array([20.8, 20.9, 22.9, 25.2, 26.9, 28.3, 29.5, 30.7, 31.8, 32.9, 34.0, 35.3, 36.4, 37.5, 38.6, 39

问题 I'm getting an error while running an application in Xcode 6 for iOS 8 simulator. The error states that 'Unable to boot device in current state: Creating' .

问题 I have an extension method like public static class Extension { public static string GetTLD(this string str) { var host = new System.Uri(str).Host; int index = host.LastIndexOf('.'), last = 3; while (index >= last - 3) { last = index; index = host.LastIndexOf('.', last - 1); } var domain = host.Substring(index + 1); return domain; } } And I am calling this like string domain = "." + _url.GetTLD(); I am getting no error at building and clean build.

问题 This error occurs during run time, and I'm not sure what's causing it - the code looks correct to me. #include <iostream> #include <string> using namespace std; struct Room { int d_noSeat; bool d_hasProjector; Room() = default; Room(const Room& r); }; class Event { Room* d_room; std::string d_name; public: Event(); Event(const Event& e); ~Event(); void set(Room r, const std::string& name); void print(); }; Event::Event() : d_room(0), d_name("") {}; void Event::print() { std::cout << "Event: "

Depending on the original number, I will get an error saying fatal error: Can't form range with end < start This happens almost every time, but for some numbers it works fine. The only numbers I have found to work with it are 9, 15, and 25. Here is the code: let num = 16 // or any Int var primes = [Int]() for i in 2...(num/2) { if ((num % i) == 0) { var

问题 I'm writing a program that will read a text file containing 5,163 names. (text file can be seen here) Then I want to store the names into a list called 'names', afterwards, I sort the list based on how many letters the name contains, shorter names are at the start of the list and the longer ones are at the end.
