Never mind. This algo doesn't work properly. Apologies.

By the algo I gave :
1. Grouping -
3 digits - 111
1 digit - 6,5,9
2. Sorting within each bucket
3 digits - 111
1 digit - 5,6,9
3. Concatenation by descending order of number of digits, and increasing
order within each digit bucket -
Grouping would then be - 3 digit numbers in sorted order follow
Another method -
1. Group the numbers according to the number of digits (maybe hash buckets)
2. Sort in ascending order within each bucket (any efficient sorting algo)
3. Concatenate them by descending order of number of digits, and ascending
order within the group.

A substring is continuous, whereas a subsequence is discontinuous. alevela
is a palindromic subsequence, and not a substring.
