Count Number of Good Subsequences | Dataford Interview Questions

Solve the problem to count the number of good subsequences.

Given a binary string s, count distinct non-empty subsequences that begin with 1. Return the count modulo 10^9 + 7.

Implement def count_good_subsequences(s):, where s is a string containing only 0 and 1, and the return value is an integer.

1 <= s.length <= 1000
s contains only the characters '0' and '1'
Count distinct subsequences, even when they can be formed from different index selections
Return the result modulo 10^9 + 7
