Given the following Node: struct Node { int data; Node* next; Node* prev; Node(int data) { this->data = data; next = nullptr; prev = nullptr; }; }; and code snippet: Node* n1 = new Node(1); Node* n2 = new Node(2); Node* n3 = new Node (3); n1->next = n2; nl ->prev = n3; n2->next = n3; n2->prev = n1; n3 ->next = n1; n3->prev = n2; Node* current = n1; for(int i = 0; i data; current = current->next; } for(int i = 0; i data; current = current->prev; } What would be the output? What is the output of the following code? void Foo(int x) { X *= 2; } void Bar(int* y) { *y *= 3; } int main() { int array[5] {5, 10, 15, 20, 25}; Foo(array[@]); Foo(array[2]); Foo(array[4]); Bar (&array[1]); Bar (&array[3]); int sum = 0; for (int i = 0; i Stage 1: [Select]
