Hi, I was wondering if you could tell me the number of operations it takes to run this code?
def large_matrix(matrix: list[list[int]]) -> int:"""Returns the area of the rectangle in the area of a rectangle is defined by number of 1's that it contains.The matrix will only contain the integers 1 and 0.>>> case = [[1, 0, 1, 0, 0],... [1, 0, 1, 1, 1],... [1, 1, 1, 1, 1],... [1, 0, 0, 1, 0]]>>> largest_in_matrix(case1)6"" You must use this helper code: def large_position(matrix: list[list[int]], row: int, col: int) -> int: a = rowb = colmax = 0temp = 0rows = len(matrix)column = len(matrix[a])while a < rows and matrix[a][col] == 1:temp = 0while b < column and matrix[a][b] == 1:temp = temp + 1b = b + 1column = ba = a + 1if (a != row+1):temp2 = temp * (a - row)else:temp2 = tempif max < temp2:max = temp2b = colreturn max """ remember: Please do this on python you should not use any of the following: dictionaries or dictionary methods try-except break and continue statements recursion map / filter import""'
Question) Consider the following code snippet: 1. List<Integer> list = new ArrayList<>();2. list.add(10);3. list.add(new Integer(10));4. list.add(new Integer(Integer.parseInt("10"))); Which line is an example of auto-boxing? Line 1 Line 4 Line 2 Line 3
Are they equivalent? 1) ArrayList<?> list = new ArrayList(); 2) ArrayList<? extends Object> list = new ArrayList<>();
Given the following class declaration: class List { public: List(); List(const List&); List& operator=(const List&); -List(); // Inserts element in the specified position, returns true if // it was able to insert. // Example, if the list is [4, 2, 1], and the user // calls list.Insert(6, 1) the list would become [4, 6, 2, 1] bool Insert(double element, size_t position) ; // Returns the position of element if found, if not found returns -1 int Index0f(double element)const ; // Removes the element in the given position double Remove(size_t position) ; // Gets the number in the given position double Get(size_t position)const ; // Returns a string representation of the list, elements // separated by commas and the list between brackets string ToString()const ; // Returns the number of elements in the list size_t Size)const; // Returns true if the list is empty, false otherwise bool IsEmpty)const; // Clears the whole list void Clear(); private: struct Node{ double number; Node* next; };…
To declare an array of String called myStrings, we would code: ArrayList<Blank 1> myStrings = Blank 2 ArrayList<String>();
Examine the following code: ArrayList<String> list = new ArrayList<String>(10) ; list.add("A"); list.add("B"); list.add("C"); list.add(0, "E" ); What element will be at index 2 of the list? What list will be printed after executing the method list.remove(2);
This code is not in order! Put the code in order! ArrayList<String> list = new ArrayList<>(); position 11 Position 1. Reorder Choice: list.remove(2); list.remove(2); position 22 Position 2. Reorder Choice: list.add("Minfilia"); list.add("Minfilia"); position 33 Position 3. Reorder Choice: list.add("Yda"); list.add("Yda"); position 44 Position 4. Reorder Choice: System.out.println("Print 3: " + list); list.add("Thancred"); // on a single line to remove variability, yes this is allowed. System.out.println("Print 3: " + list); list.add("Thancred"); // on a single line to remove variability, yes this is allowed. position 55 Position 5.
