[Solved] Unable to convert this Swift 2 code to Swift 3

[ad_1] That line should have failed under any version of Swift for being so unwieldily. First off, safely unwrap the optional. And only use one cast at the end. func isLight() -> Bool { if let components = self.cgColor.components { let brightness = CGFloat((components[0] * 299 + components[1] * 587 + components[2] * 114) / … Read more

[Solved] What is the encoding of Java byte type?

[ad_1] Bytes don’t have an encoding. They’re bytes. See the Javadoc of String.getBytes(): Encodes this String into a sequence of bytes using the platform’s default charset So, it’s whatever your default charset is. You can find out what that is at runtime using Charset.defaultCharset(). If you want the bytes in a particular charset, specify it, … Read more

[Solved] What variations of vector-like containers already widely established? Do I have to write my own? [closed]

[ad_1] Here are the ones I know of: Traditional a.k.a. plain a.k.a. C array vector unique_ptr with an array-type template argument array valarray dynarray static_vector (see also here) small_vector stable_vector There are also “variable-length arrays” and “arrays with runtime bounds”, which do not exist in C++; the former exists in C. See also this question … Read more

[Solved] Do the projection (with Jacobian) and marginalisation (inversion of matrix and remove a row/column and reinversion) commute?

[ad_1] To do np.dot last dimension of first matrix must be the same as first dimension of second one. They are not, so you are getting ValueError, that shapes are not aligned. Everything seems to be fine as you printed, but then you forgot about lines: j_temp = np.copy(J_2_SYM) # Add row/col into J_2_SYM j_temp … Read more

[Solved] How join a list of raw strings? [closed]

[ad_1] The join command works fine, but when you print the string, it cares about special characters so puts a new line whenever encounter to \n. But you can change the print behavior to escape special characters like this: Use repr: a = “Hello\tWorld\nHello World” print(repr(a)) # ‘Hello\tWorld\nHello World’ In your source code it would … Read more

[Solved] Why ArrayIndexOutOfBound Exception can be caught in Java, but C++ program crashes instead? [duplicate]

[ad_1] Since you were asked this question in an interview, the interviewer was probably trying to gain some knowledge about your understanding of principles behind C++ design. In this case, the principle the interviewer was looking to discuss is that in C++ you don’t pay for things that you do not explicitly request. Although bounds … Read more

[Solved] I have an interface’s method that can’t be called [duplicate]

[ad_1] The problem is that the compiler tells me that he “cannot resolve the method beStored(int). That simply means that you’re attempting to pass an int type to the beStored method. If you look at the interface definition of this method again you’ll notice that you’re not obeying the contract that has been set. public … Read more

[Solved] Identation Error

[ad_1] Your code, properly indented, should look like this: def update_bullets(bullets): “””Update position of bullets and gets rid of old bullets””” #Update bullet position bullets.update() # Get rid of bullets that had dissapeared for bullet in bullets.copy(): if bullet.rect.bottom <= 1: bullets.remove(bullet) print(len(bullets)) Python code requires proper indentation at all times. Whitespace matters (unlike C)! … Read more

[Solved] My basic cipher based encryption method in C++ is not working properly, how can I fix it? [closed]

[ad_1] I suggest placing all your valid characters into a string, then using the % operator. const std::string valid_characters = “abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*”; const unsigned int shift_offset = 13; std::string::size_type position = valid_characters.find(incoming_character); position = (position + shift_offset) % valid_characters.length(); char result = valid_characters[position]; You will have to check the position value because find will return std::string::npos … Read more
