Count Subsequences Divisible by N Using Dynamic Programming in Java
Count Subsequences Divisible by N is a Dynamic Programming problem where we need to count the number of non-empty subsequences of a numeric string whose numeric value is divisible by a given integer n. The solution uses remainder-based DP to efficiently track subsequences for each possible remainder instead of generating all subsequences. The approach runs in O(|s| × n) time and O(n) space and handles large inputs efficiently.
