If I want to change the for loop to for(int i; i < ...; i++), how could I write it
private Set<Rule> getRules() {
Set<Rule> ruleSet = new HashSet<>();
for (Document document : documents) {
LinkedList<String> lhs = (LinkedList<String>) document.get("r_lhs");
LinkedList<String> rhs = (LinkedList<String>) document.get("r_rhs");
Set<String> LHSSet = new HashSet<>(lhs);
Set<String> RHSSet = new HashSet<>(rhs);
Rule newrule = new Rule(LHSSet, RHSSet);
ruleSet.add(newrule);
}
return ruleSet;
}private Set<Rule> getRules() {
Set<Rule> ruleSet = new HashSet<>();
Document document;
for(int i = 0;i<documents.size();i++){
document = documents[i];
LinkedList<String> lhs = (LinkedList<String>) document.get("r_lhs");
LinkedList<String> rhs = (LinkedList<String>) document.get("r_rhs");
Set<String> LHSSet = new HashSet<>(lhs);
Set<String> RHSSet = new HashSet<>(rhs);
Rule newrule = new Rule(LHSSet, RHSSet);
ruleSet.add(newrule);
}
return ruleSet;
}

How would I add a line to the main function to sort the people vector by Age using the STL sort function? #include <iostream> #include <algorithm> #include <vector> #include <string> using namespace std; struct Person { string name; int age; string favoriteColor; }; bool sortByName(Person &lhs, Person &rhs) { return lhs.name < rhs.name; } bool sortByAge(Person &lhs, Person &rhs) { return lhs.age < rhs.age; } bool sortByColor(Person &lhs, Person &rhs) { return lhs.favoriteColor < rhs.favoriteColor; } int main() { vector<Person>...
C++ When running my tests for my char constructor the assertion is coming back false and when printing the string garbage is printing that is different everytime but i dont know where it is wrong Requirements: You CANNOT use the C++ standard string or any other libraries for this assignment, except where specified. You must use your ADT string for the later parts of the assignment. using namespace std; is stricly forbiden. As are any global using statements. Name the...
how do i change this code from for loop and if to while and break? public static boolean disjoint(Collection<Integer> coll1, Collection<Integer> coll2) { var set1 = new HashSet<>(coll1); var set2 = new HashSet<>(coll2); for (Integer s : set1) { if (set2.contains(s)){ return false; } } return true; }
C++ LinkedList I need the code for copy constructor and assignment operator #include <iostream> #include <string> using namespace std; typedef string ItemType; struct Node { ItemType value; Node *next; }; class LinkedList { private: Node *head; // You may add whatever private data members or private member functions you want to this class. void printReverseRecursiveHelper(Node *temp) const; public: // default constructor LinkedList() : head(nullptr) { } // copy constructor LinkedList(const LinkedList& rhs); // Destroys all the dynamically allocated memory //...
I have a question in how to create a method. For example there is a LinkedList of Objects, say and Object is public class Dog; private String name; private int age I want my method to take a dog age, and return the position (int) of the dog with that age has in the list example; //takes a dog age and returns position in the list, if no age in the list of dogs with age, method returns -1 public...

I need help with my Java code. A user enters a sentence and the program will tell you what words were duplicated and how many times. If the same word is in the sentence twice, but one is capitalized, it will not count it as a duplicate. How can I make the program read the same word as the same word, even if one is capitalized and the other is not? For example, "the" and "The" should be counted as...
