[Leetcode] Thoughts on solving Distinct subsequences

Given a string S and a string T, count the number of distinct subsequences of T in S.A subsequence of a string is a new string which was formed from the original string by deleting some (can be none) of the C Haracters without disturbing the relative positions of the remaining characters. (ie, is a subsequence of and is not "ACE" "ABCDE" "AEC" ).Here are an example:S = "rabbbit" , T ="rabbit"Return 3 .Question: Given the string s, T, how many different sub-sequences in s are available for T.The
