For each character in the given string, it has two options either it will be in the subsequence or will not be in the subsequence, because for this reason, we need to backtrack the solution. Pseudo Code We decl
Learn how to print all subsequences of a string in C++ with this comprehensive guide, including code examples and explanations.
828. Count Unique Characters of All Substrings of a Given String # 题目# Let’s define a function countUniqueChars(s) that returns the number of unique characters on s, for example if s = "LEETCODE" then "L", "T","C","O","D" are the unique characters since t...

Calculate the total number of all common subsequences between a string and a vector/list of strings. Subsequences can be interrupted by items, i.e. q-w is considered a subsequence of q-e-w-r

Given two strings A and B of lengths na and nb, na⩽nb, respectively, the all-substrings longest common subsequence (ALCS) problem obtains, for every substring B′ of B, the length of the longest string that is a subsequence of both A and B′. The ALCS problem has many applications...

To validate your method, however, it is necessary to write a program that checks if the message is really encoded in the final string. Given two strings s and t, you have to decide whether s is a subsequence of t, i.e. if you can remove characters from t such that the ...
