C++ Program to find out the maximum rated parts set
Suppose, there is a manufacturer that makes specific parts for a particular product. The manufacturer has n different variations of the parts, and the parts have a specific rating on three criteria. The ratings of the n products are given in the array 'ratings' where each element is of the format (A, B, C) where A, B, and C are different rating criteria of the product. Now, an OEM wants to buy m parts for each product they make from the manufacturer of the parts. The OEM chooses the parts satisfying the below conditions −Two or more units of the ...

Suppose, there are n cities and m roads are connecting them. Each road is unidirectional, and it takes a particular amount of time to reach from the source city to the destination city. The information of the roads is given in the array roads where each element is of the format (source, destination, time). Now, a person is traveling from one city to another city and the trip has to be a round-trip. A trip can be called round-trip when the person starts from a particular city, goes through one or more roads, and finishes the trip in the same ...

Suppose, we have a permutation of integers 'seq' and an array of integer pairs 'pairs' of size m that contains integers 0 to n - 1. Now, we perform the following operation on seq as many times as possible so that seq[i] = i (0 ≤ i < n) is maximized.We have to choose an integer j where 0

Suppose, we are given 2n number of coordinates on a two-dimensional plane. The 2n coordinates are divided into two arrays coordA, and coordB. The coordinates are represented as integer pairs. Now we have to form coordinate pairs that will contain one point from coordA and one point from coordB. We can make pairs if and only if the x coordinate of the point from coordA is smaller than that of the point from coordB, and the y coordinate of the point from coordA is smaller than that of the point from coordB. We have to find out the number of ...
Read MoreC++ program to find out the maximum sum of a minimally connected graph
Suppose, we are given a minimally connected graph. That means removing any edge will make the graph disconnected. The graph has n vertices and the edges are given in an array 'edges'. There is also an array 'vertexValues' given to us that contain n integer values.Now, we do the following −We write a positive integer on each of the vertices and then try to calculate a score.There is an edge connecting two vertices, we put the smaller value of the two vertices on the edges.We calculate the score by adding all the edge values.We have to find the maximum value ...
Read MoreC++ Program to find out the cost to travel all the given coordinates
Suppose, we are given n three-dimensional coordinates. The cost to travel from coordinate (a, b, c) to (x, y, z) is ∣ x − a∣ + ∣ y − b∣ + max(0, z − c). We start from the first coordinate, then visit all the coordinates at least once, and then return to the first coordinate. We have to find out the total cost of this whole trip. The coordinates are given to us in the array 'coords'.So, if the input is like n = 3, coords = {{1, 1, 0}, {1, 3, 4}, {3, 2, 2}}, then the output ...
