When the robot reaches the gray square, it turns around and faces the bottom of the grid. Which of the following changes, if any, should be made to the code segment to move the robot back to its original position in the bottom-left square of the grid and facing toward the bottom of the grid? A) Interchange the ROTATE_RIGHT and the ROTATE_LEFT blocks. B) Replace ROTATE_RIGHT with ROTATE_LEFT. c) Replace ROTATE_LEFT with ROTATE_RIGHT. D) No change is needed; the algorithm is correct as is.

1. Your objective is to guide a robot through a labyrinth. 1. Your objective is to guide a robot through a labyrinth. The robot begins at the maze's middle, looking north. You have the option of facing the robot north, east, south, or west. You may tell the robot to travel ahead a particular distance, but it will halt if it comes too close to a wall. i. Create a problem statement for this situation. What is the size of the state space? ii. The only location we need to turn while traversing a labyrinth is at the junction of two or more passageways. This remark may be used to reformulate the issue. What is the current size of the state space? iii. We may go in any of the four directions from any point in the labyrinth until we reach a turning point, and that is the only action we need to do. Using these steps, rephrase the issue. Is it necessary to maintain track of the robot's orientation at this point? iv. We already abstracted from the actual world in our original description…
Creating decagons There are 1000 points in the plane, no three of them on the same line. Devise an algorithm to construct 100 decagons with their vertices at these points. The decagons need not be convex, but each of them has to be simple, i.e., its boundary should not cross itself, and no two decagons may have a common point.
The mid-point circle algorithm makes use of the function f(x,y)=x2+y2-r2. Given r = 2, determine whether the following pixels are inside, outside or on the boundary of the circle:i. (1,-3)ii.

A robot starts on a point marked “A” on a rectangular grid of points. The starting point is always the top left point on the grid. The robot can move left, right, up or down, moving from one point to the next. By moving in steps going left, right, up or down, the robot would like to reach a point marked “B”, which is always the bottom right point in the grid. Sometimes, points are marked as “x”, and the robot is not allowed to visit them at all. A robot is never allowed to visit a point more than once. In how many ways can the robot move from A to B and visit all points along the way? For example, in the following grid, represented in text as A . . . . B there is only one path from A to B: In the following grid, represented in text as A . . x x B there is still only one path (we're lucky because of the two x's): However, in the grid A . . . x B there are no ways for the robot to move from A to B and visit all points that are not marked with “x”. Write a single…

Correct answer will be upvoted else downvoted. Computer science. Koyomi has recently gotten the three brief strings from the challenge coordinators. Assist her with composing a substantial novel for the challenge. A string a will be an aftereffect of a string b if a can be acquired from b by erasure of a few (perhaps, zero) characters. Input The principal line contains a solitary integer t (1≤t≤104) — the number of experiments. The principal line of each experiment contains a solitary integer n (1≤n≤105). Every one of the accompanying three lines contains a bitstring of length 2n. It is ensured that these three strings are pairwise unmistakable. It is ensured that the amount of n across all experiments doesn't surpass 105. Output For each experiment, print a solitary line containing a bitstring of length at most 3n that has somewhere around two of the given bitstrings as aftereffects. It very well may be demonstrated that under the imperatives of the…
