An autonomous robot is being designed to step through a simple 2d obstacle course (that is a flat maze). for each step, the robot scans three points: in front, to the left and to the right. the robot stores the results of the scan in a 1x3 vector (v) where each cell is occupied by either a o if no wall is scanned or a 1 if a wall is scanned (see figure 1 for an example). when there is no wall is in front of the robot, then the robot continues to step forward. when the front of the robot is blocked, then the robot turns to face the direction without a wall present. if the robot could turn left or right, then it chooses a random direction. when the robot reaches a dead end, the robot turns by 180 degrees and steps back the way it came. 1. write an algorithm that determines whether the input vector, v is in the correct format (must be a 1 x 3 vector containing only ones and zeros).
