Hi, here’s your problem today. This problem was recently asked by Apple:

Given a string, we want to remove 2 adjacent characters that are the same, and repeat the process with the new string until we can no longer perform the operation.

Here’s an example and some starter code:

def remove_adjacent_dup(s):

Fill this in.


Start with cabba

After remove bb: caa

After remove aa: c

print c
