Question 1 \( \begin{array}{ll}1 & \text { #Read only region start } \\ 2 & \text { class UserMaincode(object): }\end{array} \) How to Attempt? Boring Day Ron was getting bor him with a question. distinct subsequences the string itself. A subsequence is a sequence of characters which can be found in the string (example: In "abcd" some subsequences can be "ac", "bd", "abd", "acd" etc.) A string \( S \) is lexicographically greater than string T if S appears after T when arranged in a dictionary-like format. Ron needs your help to solve this question. Input Specification: input1: The string for which the subsequences have to be found. Output Specification: The number of distinct subsequences lexicographically larger than t:
Example 2: input1: \( a b c \)
Example 2: input1: \( a b c \) Output: 4 Explanation: Here, the subsequences are \( \{a\},\{b\},\{c,\{a b\},\{b c\},\{a c\},\{a b c\} \) and \( \{b\},\{c\},\{b c\},\{a c\} \) are larger than abc.
