Here is the question given by Uber interview -

/**

• Write a comparator that takes two strings and returns a standard integer value:

•      something negative if the first string is "smaller,"

•      zero if they are "equal," 

•      and something positive if the first string is "larger." 
• We want to agree with the standard comparator for all cases except one:
• if we encounter a consecutive string of integers, we want to read it for its numeric value,
• and use that as the comparison.
• For instance, in the standard string comparator, "a1b" comes before "a10b", because 'a' == 'a' and '1' < '10'.
• In our string ordering, I want to reverse this, instead parsing it so that we see 'a' == 'a', but 10 > 2.
