Why is this code not working?

#1

It is giving me the correct output with Sample Test Cases, and other test cases as well. But at Hackerblocks it is not accepting.
Here’s the link to my code. https://ide.codingblocks.com/s/87938

@raghav6 hey raghav let consider the following case
8
1 34 3 98 9 76 45 4
if you sort these numbers then
sorted number is
1 3 4 9 34 45 76 98
now reverse
987645349431
but actually the output should be
998764543431
now design a compare function which will passed with sort function
your implementation will not work

#3

Used a custom comparator and it worked. Thanks!

@raghav6 happy coding !
