To sort the list which consists of collections of integer values.
sort() function will consider values in the list as String not the integers values. So sort() function to understand, string to integer values we need to use Space-ship operator i, e. sort {$a <=> $b}.

@no = (5, 4, 3, 2, 1);
print "Original list is : @no\n";
@sorted_no = sort {$a <=> $b} @no;

print "Sorted numbers are: @sorted_no\n";

Output:
Original list is : 5 4 3 2 1
Sorted numbers are: 1 2 3 4 5

Given the list contains (10, 13, 1, 2, 9), the sorted_number seems to treat all element as string after sort.

I'm not sure why the code below is not giving sorted output!
Can anyone assist?

@nums = (23, 4, 35, 26, 23, 346, 35);
@sorted_nums = sort @nums;
