C++ A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program. A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary! or Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin! About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".

fix the code below to do a reverse number, you can add max 2 lines of code and also change max 2 lines of code. code: public class Main { public static void main(String[] args) { solution(29020714); solution(-364); solution(514820); solution(16091900); } static void solution(int N) { int enablePrint = 0; while (N > 0) { if (enablePrint == 0 && N % 10 != 1) { enablePrint = N / 10; } if (enablePrint > 0) { System.out.print(enablePrint); } N /= 10; } System.out.println(); } }

Write a function called monkey_experiment that takes in a goal string (e.g., "methinks it is like a weasel") and a number of iterations as an argument. Run the experiment for that many iterations, and return a tuple with the highest-scoring text that was generated along with the score that it got. Test results: >>> monkey_experiment("methinks it is like a weasel",100000) ('m ojindoebjrerloiuc m oaanvl', 8) >>> monkey_experiment("methinks it is like a weasel",100) ('yeanpqj twosisjcvqrrfu eagbi', 5) >>> monkey_experiment("brevity is the soul of wit",100000) ('nnebptorcrytbe wogl uygdsn', 8) >>> monkey_experiment("to be",100000) ('tofbe', 4) >>> monkey_experiment("to be",200000) ('tbhbe', 3) >>> monkey_experiment("to be",500000) ('eo be', 4)
