- Subsequence and Substring - GeeksforGeeks
A subsequence is a sequence that can be derived from another sequence by removing zero or more elements, without changing the order of the remaining elements More generally, we can say that for a sequence of size n, we can have ((2^n)-1) non-empty sub-sequences in total For the same above example, there are 31 sub-sequences
- What is a subsequence in calculus? - Mathematics Stack Exchange
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements Formally, a subsequence of the sequence $(a_n)_{n \in \mathbb{N}}$ is any sequence of the form $(a_{n_k})_{k \in \mathbb{N}}$ where $(n_k)_{k \in \mathbb{N}}$ is a strictly increasing sequence of positive integers
