### Decode Ways #### Problem Statement You are given a string `s` that represents a sequence of numbers from 1 to 9 repeated some number of times. A valid sequence is one where each number in the sequence is valid, and each number has a valid number of repeating preceding digits that it can be decoded as. A number `c` that repeats `n` times can be decoded as the number `nc`. If a number `c` can be decoded as multiple values (e.g., '26'), it can only be decoded as one value in the sequence. #### Rules and Constraints - A number can have values from 1 to 9. - The number in `s` must start with a character that can be decoded as a valid number. - Each number in `s` must be valid and can be decoded as a sequence of preceding repeated digits. - The string `s` is composed of only digits in the set [1-9]. - There will not be more than `100` digits in the string `s`. - The function should return the total number of valid sequences that `s` can be decoded as. #### Time/Space Complexity The time complexity should be O(length of `s`), and the space complexity should be O(length of `s`), as only a single pass is needed to traverse the string and store the intermediate results if a dynamic programming approach is taken. ### Example **Input:** {"input_data":[1,2,3]} **Output:** [1,2,3]
