In C++, if you have a C++11 capable compiler and you use std::vector instead of raw arrays, you could use initializer lists: void kilos(const std::vector<int> percentage, const std::vector<std::string> liquid); // … kilos({40, 60}, {“water”, “milk”}); solved Syntax for arrays as operands
Aside from using two separate loops, the original code contains lots of redundant statements. One possible improvement would be this: int tmp = 6 * h; for (j = 1; j <= 4; j++) { a[j] = tmp; b[j] = 6 + 3 * j * j; } The main optimizations: One loop instead on … Read more
Java is not able to read/write to an arbitrary position in the RAM. If you want to share data between different applications, I recommend using a file or a database. solved Write data directly to RAM in Java, and then read it? [closed]
There is a popular math theorem – Fermat’s Great (Last) Theorem – that states for any integer n > 2 there does not exist non-zero integers a, b, c such that a^n + b^n = c^n. 2 solved consider x^i+y^i=z^i, x
From the code posted, i assume messages is a list of dicts. key_list = [data[key1], data[key2]] for msg in messages: if msg[‘name’] in key_kist: msg[‘Flag’] = 2 solved How to change only the last repeated value from a list of dictionaries?
If you need to be able to reference lil_patate elsewhere in your code then you can’t make this factorisation at all. If you don’t need to refer to lil_patate elsewhere then get rid of it and initialise patate directly from q_nutrients: string patate(to_string(q_nutriments)); However, while this may improve the readability of the code, it doesn’t … Read more
It is not possible to put generic constraint about specific constructor availabilty, so you cannot guarantee inside the method that TDal _dal = new TDal(_connectionString); is possible. I would refactor it then to provide dal externally: public List<TRule> getData<TRule>(TRule perRA, IDal<TRule> dalRA, int acao) { List<TRule> list = new List<TRule>(); try { list = dalRA.getDATA(perRA, … Read more
The code you presented here is wrong. First off, you need to read a little more of the documentation. Here is a useful link: Painting and Drawing. Basically there are two ways to update a window: In response to the WM_PAINT message. Use the BeginPaint and EndPaint functions to paint the client area properly. This … Read more
BigInteger has the divideAndRemainder(…) method, one that returns a BigInteger array, the first item the division result, and the second, the remainder (which is what mod really does in Java). Update Including comment by Mark Dickinson to other answer: There’s a much simpler linear-time algorithm: set acc to 0, then for each digit d in … Read more
First of all, here is a scheme that doesn’t work on its own because it ignores the constraints on maximum inflow and outflow rates, so it solves an easier problem. The tricky bit here seems to be which tank to use when. It looks like tanks with lower values of Ui are better. If you … Read more
Your code is pretty fast (O(n)), but this problem can be solved in constant time (O(1)), since it is just based on the condition of the intersection of two lines being an integer. static String kangaroo(int k1, int v1, int k2, int v2) { float x = (k2 – k1)/(v1 – v2); if(x == (int) … Read more
Why doesn’t std::vector or other containers have length as a member variable, instead of a function? Because it would be writable if it was a public member variable. Since it makes no sense to write to the size member of a vector, the designers made the size member private and provided a size() method to … Read more
Attempting to read an uninitialized variable that never had its address taken triggers undefined behavior, which basically means that the program is not required to behave in any particular way. It’s clear that you were attempting to have the uninitialized variable x in the function x to get the “left over” value of x in … Read more

Ok, I know how much you loved my 10000 checkboxes so since I recently moved to 50000 checkboxes I figured it would be fun to post an answer (maybe I’ll get enough downvotes to keep me going till the ultimate target of 100000 checkboxes on a single page). I updated the HTML since last time … Read more
