Append Characters to String to Make Subsequence
Understand how to solve problems that involve making one string a subsequence of another by appending characters. Learn to apply the two-pointer approach to efficiently find the minimum characters needed to modify the source string so it contains the target subsequence, preparing you for related coding interview questions.
