Problem 2 (6 points)

Write three Python functions which take a path of a random walk as an input and then compute the values of the random variables C2N,L2N,M2NC2N,L2N,M2N, respectively, as defined above:

### Insert your code here for total time spend above zero def timeAboveZero(path): ## Write your own code here return result

### Insert your code here for last time the random walk visited zero def TimeOfLastVisitOfZero(path): ## Write your own code here return result

### Insert your code here for the time when the random walk hits its maximum def timeHitMax(randomWalk): ## Write your own code here return result
