Given a string S and a string T, count the number of distinct subsequences of S which equals T. A subsequence of a string is a new string which is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining ...

Different PTM designs have been proposed,49 all of which have in common that they contain three key elements: a trans-splicing domain for spliceosome recognition and splicing, one or two binding domains complementary to one or two intronic subsequences of the target’s pre-mRNA, and a codin...
Let’s denote dp[i][j] as the amount of distinct subsequences in s[:i] which can construct t[:j]. So we can get the state transition function dp[i][j] = s[i - 1] == t[i - 1] ? (dp[i - 1][j - 1] + dp[i - 1][j] : dp[i-1][j]. Also for the initial val...

|b|≥3|b|≥3) of sequence aL,aL+1,…,aRaL,aL+1,…,aR.However, he hates monotone stuff, and he wants to find a subsequence free from monotone triples. Besides, he wants to find one subsequence with the largest length among all subsequences free from monotone triples for every query....
Let's solve the task for a sequence of a pairwise distinct numbers and then change the conditions to a general sequence. Let's fix \(a_i\) — the leftmost element of \(b\) and look at what we are asked to find. So there should be some position \(j\) to the right of \(i\...
