Advertisements Can anyone tell me what have I done wrong in this code ? In this approach, I traverse the array and, as soon as I find a 0 element, I traverse to the right of the 0, and swap it with the 1st non-0 element found. class Solution { public void moveZeroes(int[] nums) {… Read More Move all zeroes to the end of an array with the order of the elements preserved

Advertisements What are the contents of a[]? int a[ ] = {4 , 9, 1, 8, [0]=5, 7}; I tried printing it out with: int main () { int a[ ] = {4 , 9, 1, 8, [0]=5, 7}; for(int i = 0; i < 10; i++) { printf("%d\n", a[i]); } return 0; } The… Read More What is the new content of an array if I redefine a value of an array inside that same array in C?

Advertisements I’ve been trying to swap array strings without using string.h or something else. I wrote some code but it only changes the word’s first letter. Where did I make a mistake? My code is: #include <stdio.h> #define SIZE 25 void strswap(char [], char []); int main(void) { char str1 [SIZE], str2 [SIZE]; printf("enter the… Read More Swapping array problems in c

Advertisements I’ve been going through the base code of some Rust library (Carboxyl) and found some weird code. It performs a filter map to a Vector after swapping it with an empty one and reassigning the result to the original identifier. impl<A: Send + Sync + Clone + ‘static> Source<A> { /// Make the source… Read More What would be the benefit of binding result of operation to it self after mem_swap with empty one

Advertisements I have a List called myqueue and I’m trying to swap the values of two specific indexes in my List. Here is what I have so far: private Comparator<T> cc; private List<T> myQueue; private void exch(int i, int j) { // helper method to exchange items at indices i and j T temp =… Read More How can I swap the values of specific indices of my List

Advertisements The following code, which std::swaps two std::priority_queue<int, std::vector<int>, decltype(some lambda)> results in a compiler error in C++17, but not in C++20. #include <queue> int main() { auto cmp = [](int x, int y) {return x > y;}; std::priority_queue<int, std::vector<int>, decltype(cmp)> pq1(cmp), pq2(cmp); std::swap(pq1, pq2); // adding this line results in an error return 0;… Read More std::swap of std::priority_queue with lambda comparator compiles under C++20 but not C++17: "error: object of type value_compare cannot be assigned"

Advertisements I am trying to write a function that swap two arrays in O(1) time complexity. However, when i try to write the function parameters, I get the error: error: cannot convert ‘int (*)[4]’ to ‘int**’ Here is my code: #include <iostream> using namespace std; void swap_array_by_ptr(int* a[], int* b[]) { int* temp = *a;… Read More error: cannot convert ‘int (*)[4]’ to ‘int**’ | SWAPPING ARRAYS

Advertisements I am looking for a way to insert some artificial delays when the operating system access the Swap Space. I am working on the latest version of kernel (Version 6.0.6 right now), I have found some locations in the kernel open source code that it handles page faults (do_page_fault()), but I am not sure… Read More How to insert a delay in accessing swap space using Kernel Linux (6) source code?

Advertisements could anyone explain me, why is it not possible to swap list positions in my function for selection sort? This is what i wrote at first, but the function returns the same list as the input: def selection_sort(list): for i in range(0, len(list)): minimum = list[i] for j in range(i + 1, len(list)): if… Read More Python – switching positions: list[i], list[list.index(minimum)] = list[list.index(minimum)], list[i]
