![(Rudin, Ch. 6, Exercise 6) Divide the unit interval [0, 1] into thirds and remove the open interval
G,). What remains is a pair of closed intervals, each of them one-third as long as the original. For
each of the remaining intervals, do this again, i.e., divide the interval into thirds and remove the open
middle interval. Repeating the process over and over again, what is left in the limit is the Cantor
middle-thirds set C.

Expert Solution

Step 1
Given that:
The interval [0,1] is given. divide the [0, 1] into 3 subintervals and delete the open middle subinterval and delete the open middle subinterval (1/3, 2/3), leaving two intervals [0,1/3] U [2/3, 1]
Now, again divide each of the 2 resulting intervals above into the open middle third subinterval of each subinterval of each interval obtained in the previous step.
And continue the process, and each step, delete the open middle third subinterval of each interval.
Here objective is to find the limit of the Cantor middle-thirds set C.
