Convex Hull

For a given set of points S in a plane, the convex hull is a line completely enclosing all the points within the plane such that no concavities are left. In other words, the convex hull of a set of points is the smallest convex polygon consisting of all points within the plane.

Maze Runner Function - Implementation of this function is done in a1_partd.py We describe a maze as having row x col cells. For example if row was 3, and col was 4, then we would have a grid of cells as follows. We describe a wall by the two cell numbers the wall separates. If every single wall existed, there would be (row-1)(col) + (col-1)(row) walls. 0 | 1 | 2 | 3 4 | 5 | 6 | 7 8 | 9 | 10 | 11 A Maze class (which you do not need to implement) describes a maze as mentioned above. This class is defined in maze.py. It has methods that you can use to travel through the maze (i.e. figure out where you are, find a neighbour cell etc.) use a recursive maze runner function: def find_path(maze, from_cell, to_cell); The find_path function will find a path from cell number from_cell to cell number to_cell and will return it as a list containing all the cell numbers along the path, from the from_cell to the to_cell. You are allowed to use this function as a wrapper to a recursive function that…
In C++, can I get a code example for a function that will return the intersection items for two sets. It will return/print out the shared (intersection) items for them. I am looking for an actual function preferably for a set class, comparing one instance of a set class with another, but definitely NOT a STL keyword. Thank you.
Design a generic function that returns a minimum element from an array. The function should have two parameters. One is the array of a generic type, and the other is the size of the array. Test the function with an array of int, double, and string values.
Create a Vector2D class with properties x and y and a proper constructor method. Plus, minus and multiplication with a scalar operators should be overloaded. Create a Body class with properties of pos, vel, mass and constructor(float Mass, Vector2D Pos, Vector2D Vel), addForce(Vector2D F) and Move(float dt) methods. Your program should create an array or collection of Bodies, at each time step (dt), calculate forces that bodies exert each other and apply accordingly. Finally, in a 2D space, bodies should move freely based on their properties and applied forces. You can use option buttons or another element to represent bodies and move them inside the form.

Q8 Hive Minds: Migrating Birds You again control a single insect, but there are B birds flying along known paths. Specifically, at time t each bird b will be at position (x¿(t), Yb(t)). The tuple of bird positions repeats with period T. Birds might move up to 3 squares per time step. An example is shown below, but keep in mind that you should answer for a general instance of the problem, not simply the map and path shown below. Your insect can share squares with birds and it can even hitch a ride on them! On any time step that your insect shares a square with a bird, the insect may either move as normal or move directly to the bird's next location (either action has cost 1, even if the bird travels farther than one square).
