+you are given a string 's'. you can perform the following process on 's' any
+number of times: choose an index 'i' in the string such that there is at
+least one character to the left of index 'i' that is equal to 's[i]' and at
+least one character to the right that is also equal to 's[i]', delete the
+closest character to the left of index 'i' that is equal to 's[i]', delete
+the closest character to the right of index 'i' that is equal to 's[i]'.
