Substring Search

Given a long text t and a string s, you are asked to find all the occurrences of s in the text t. You are asked to find the starting positions in t that match s.


The first line of the input contains the text t (1 ≤ |t| ≤ ).
The second line of the input contains the string s (1 ≤ |s| ≤ |t|).


For each occurrence of s in t, output the starting position in t where it occurs. The positions should be in ascending order (from the beginning of the text to the end) separated by a space. The indexing starts from 0.
