Solution: Append Characters to String to Make Subsequence
Explore how to determine the minimum number of characters that must be appended to a source string so the target string becomes its subsequence. This lesson teaches a greedy two-pointer approach to efficiently identify matches and calculate the needed additions, helping you master string manipulation techniques for coding interviews.
We'll cover the following...
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.
Constraints:
source.length,target.length...
