an int vector is given, and I need to find the maximum sum of number sequences that are more than 3 positions away from each other. So an example: Input: 10, 5, 6, 7, 16, 18, 12 Output: 29 Explanation: candidate "routes": 10-7-12 = 29 10-16 = 26 10-18 = 28 5-16 = 21 5-18 ..

I have been asked to create a C++ program that multiplies two nxn matrices recursively using a divide and conquer algorithm for a university assignment. The pseudocode for the same looks like this: Being new to divide and conquer problems, I am finding it a bit confusing to implement.I am getting stuck in the else ..

How would you all implement this function: void fibonacci(int f[], unsigned n) with n being the first n numbers of the sequence. This must be implemented using recursion. This is what I have: void fibonacci(int f[], unsigned n) { if (n == 0) { f[n] == 0; cout << f[n] << endl; return; } else ..

I’m currently taking a class for c++ and we are learning about recursion and in class my professor used this function as an example of recursion, the function is meant to return the smallest digit in a number and is: int smallD(int n) { if (n < 10) return n; int x = smallD(n / ..

I am trying to optimise the merkle root calculation as much as possible. So far, I implemented it in Python which resulted in this question and the suggestion to rewrite it in C++. #include <iostream> #include <vector> #include <string> #include <fstream> #include <streambuf> #include <sstream> #include <openssl/evp.h> #include <openssl/sha.h> #include <openssl/crypto.h> std::vector<unsigned char> double_sha256(std::vector<unsigned char> ..

def recursiveDict(): return collections.defaultdict(recursiveDict) # I can create a dictionary like the following dic = recursiveDict() dic[‘a’] = 1 dic[‘a’][‘a’] = 1 dic[‘a’][‘a’][‘a’] = 1 dic[‘a’][‘a’][‘a’][‘a’] = 1 and so on…. I have returned to work with C++ after working for 4 years with Python and other dynamic languages. I wanted to be able to ..

The goal of this is to enumerate all the possible game boards using a tree. This is part of a larger program which consists of an AI engine that finds the optimal move in tik tac toe. I am wanting to get some help in finding a way to approach this problem. bool CompareGameTreeNodeSharedPtr::operator()(const shared_ptr<GameTreeNode> ..

Is there a way to create n for-loops and get all possible combinations of sums at every iteration based on this code. for (int i = 0; i < m; ++i) { for (int j = 0; j < m; ++j) { … for (int k = 0; k < m; ++k) { x = ..

You are given a number n, representing the number of rows. You are given a number m, representing the number of columns. You are given n*m numbers, representing elements of 2d array a. The numbers can be 1 or 0 only. You are standing in the top-left corner and have to reach the bottom-right corner. ..
