While it is not possible to write a function that simply swaps two variables, it is possible to write a helper function that allows you to: Swap two variables using only one statement Without temporary variables in the caller’s code Without ‘boxing’ primitives With a few overloads (one of them using generics), it works for … Read more
Why Infinite loop? Infinite loop is because of self loop in your list after calling swap() function. In swap() code following statement is buggy. (*b)->next = (temp1)->next; Why?: Because after the assignment statement in swap() function temp1‘s next starts pointing to b node. And node[b]‘s next point to itself in a loop. And the self … Read more
Your statement is roughly equivalent to this expanded form: x = x ^ (y = y ^ (x = x ^ y)); Unlike in C, in Java the left operand of a binary operator is guaranteed to be evaluated before the right operand. Evaluation occurs as follows: x = x ^ (y = y ^ … Read more
You can use .replaceWith() $(function() { $(“.region”).click(function(e) { e.preventDefault(); var content = $(this).html(); $(‘#map’).replaceWith(‘<div class=”region”>’ + content + ‘</div>’); }); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div id=”map”> <div class=”region”><a href=”link1″>region1</a></div> <div class=”region”><a href=”link2″>region2</a></div> <div class=”region”><a href=”link3″>region3</a></div> </div>
From python.org Assignment of an object to a target list, optionally enclosed in parentheses or square brackets, is recursively defined as follows. … Else: The object must be an iterable with the same number of items as there are targets in the target list, and the items are assigned, from left to right, to the … Read more
Check the answer from Marc from C#: Good/best implementation of Swap method. public static void Swap<T>(IList<T> list, int indexA, int indexB) { T tmp = list[indexA]; list[indexA] = list[indexB]; list[indexB] = tmp; } which can be linq-i-fied like public static IList<T> Swap<T>(this IList<T> list, int indexA, int indexB) { T tmp = list[indexA]; list[indexA] = … Read more
How is std::swap implemented? Yes, the implementation presented in the question is the classic C++03 one. A more modern (C++11) implementation of std::swap looks like this: template<typename T> void swap(T& t1, T& t2) { T temp = std::move(t1); // or T temp(std::move(t1)); t1 = std::move(t2); t2 = std::move(temp); } This is an improvement over the … Read more
The best script I found is on this page : http://northernmost.org/blog/find-out-what-is-using-your-swap/ Here’s one variant of the script and no root needed: #!/bin/bash # Get current swap usage for all running processes # Erik Ljungstrom 27/05/2011 # Modified by Mikko Rantalainen 2012-08-09 # Pipe the output to “sort -nk3” to get sorted output # Modified by … Read more
Python correctly interprets the code as if you used additional variables, so the swapping code is equivalent to: t1 = b[:,0,0] t2 = a[:,0,0] a[:,0,0] = t1 b[:,0,0] = t2 However, even this code doesn’t swap values correctly! This is because Numpy slices don’t eagerly copy data, they create views into existing data. Copies are … Read more
Here is one trick: public static int getItself(int itself, int dummy) { return itself; } public static void main(String[] args) { int a = 10; int b = 20; a = getItself(b, b = a); }
