Plz just do the 2D part

2. Random walk problem 1-D. The figure below shows a Classification yard in the railroad system. Suppose there are 2 train cabs that need to be re-connected, they will pass the start point one by one with no connection. There are 5 tracks in total, when meeting a turnout, a train cab can choose to change to another track or keep its current one. The train cab can only change to the track that is close to its current track. Assume there are 5 turnout points that a train cab can choose to change track. However, currently, there are some problems with the turnout control system, and all the turnout has been controlled randomly, which means that we don't know whether a turnout is keeping the train cab on its way or making it change the way. Simulate this process by MATLAB code. 3. Random walk in 2-D. Simulate the process of random in an 2-D space
