enter image description here in this code, as you see in this picture link I made a custom comparator for lower_bound() so it supposes to 100 as output in the end as in the lst compare 100 <=100 is true but it gives the next index 200 as output why? please explain thank you Source: ..

I have to create a binary like data structure like below:- Tree Where each node represents a user profile. When a user will create a profile, they would enter their parent’s user ID(for example A01) and choose their orientation(left/right), For example, the new user while creating their account puts in A01 as their parent and ..

The question is based on 0/1 knapsack problem. This is brief intro about 0/1 knapsack=> Given weights and values of n items, put these items in a knapsack of capacity W to get the maximum total value in the knapsack.(To know about knapsack in more detail , refer to this article> https://www.geeksforgeeks.org/0-1-knapsack-problem-dp-10/) My question: We ..

I am practising questions on Dynamic Programming and I am stuck at a probelm which is quite similar to the 0-1 knapsack problem. I am unable to pass any of the test cases even though my code works perfectly for the sample input. Please help. The Question: Cody went to the market to buy some ..

I’m trying to wrap my head around memory in C++. I’ve read that using & in a loop saves us time on heap allocation and deallocation and therefore should be used whenever possible. I’m looking at a leetcode problem I’ve just done, and not only does using & in the loop have no impact on ..

An intranet has n computers numbered 1 through n and m one-way communication links between several servers. A path of the form u, v, t represents the time it takes to transfer a file from server u to server v as t. When a computer receives a file from a given computer, it transfers that ..

I’m trying to implement a travelling courier algorithm, which is a variation of the traveling salesman problem. I have a vector of intersection ids (ints) that can either be pickup or drop-off intersections. A delivery is made when we visit the pick up intersection to pick the package, and then some time later visit the ..

enter image description here I can not get it but when i calculate it by myself the result is 1 #include <iostream> using namespace std; int main() { float x = 1.0e20f, y = 1.0f, z = 1.0e20f, u = 1.0f; cout << "the result: " << y /((x+y-z)*u) << endl; return 0; } Source: ..

I have a design dilemma when doing a vector class from a book example and started wondering, what is the rule of thumb or closest to rationalize when an algorithm or function should be a member function or not? For example, given the class: struct vector2d { float x, y; vector2d() = default; vector2d(float x, ..
