Solution: Append Characters to String to Make Subsequence
Understand how to use the two pointers technique to find the minimum number of characters to append to a source string to make a target string its subsequence. This lesson demonstrates identifying matches and efficiently completing the subsequence with a linear time and constant space algorithm.

Statement
You’re given two strings, source and target, made up of lowercase English letters. Your task is to determine the minimum number of characters that must be appended to the end of the source so that the target becomes a subsequence of the resulting string.
Note: A subsequence is formed by deleting zero or more characters from a string without changing the order of the remaining characters.
