Divide given numeric string into at most two increasing subsequences which form an increasing string upon concatenation | Function to check for valid subsequences.
Stores which element belongs to which subsequence.
Check for each pos if a possible subsequence exist or not.
Last member of 1 subsequence.
Last Member of 2 nd subsequence.
Check if current element can go to 2 nd subsequence.
Check if the current elements belongs to first subsequence.
If the current element does not belong to any subsequence.
Check if last digit of first subsequence is greater than pos.
If a subsequence is found , find the subsequences.
Stores the resulting subsequences.
Print the subsequence.
If no subsequence found , print - 1.
