Problem Statement:
There are 3 tick marks initialized and a problem expression on board. Modify each driveDistance() so that all 3 tick marks reach the same x-coordinate of the result of the given expression. The tick marks' movement should model the expression using 3 different methods.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot1;
double radius1 = 1.75;
CLinkbotI robot2;
double radius2 = 1.75;
CLinkbotI robot3;
double radius3 = 1.75;

// This is an example solution to problem: Show 20 -31
robot1.traceColor("red", 5);
robot1.driveDistance(20, radius1);
robot1.traceColor("white", 2);
robot1.driveDistance(-31, radius1);
robot2.traceColor("green", 5);
robot2.driveDistance(20 - 31, radius2);
robot3.traceColor("blue", 5);
robot3.driveDistance(20 + -31, radius3);
printf("All tick marks should end at -11");
