Solution: Distinct Subsequences
Explore a dynamic programming approach to count how many distinct subsequences of one string match another exactly. Understand how to optimize space using a one-dimensional array while maintaining correct subsequence counts. This lesson helps you apply these techniques to solve complex string matching problems efficiently.

Statement
Given two strings, s and t, determine how many distinct subsequences of s match t exactly.
Note: A subsequence is formed by deleting zero or more characters from s without changing the relative order of the remaining characters.
You may assume the result will always fit within a
