Web Reference: A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters. (i.e., "ace" is a subsequence of "abcde" while "aec" is not). In-depth solution and explanation for LeetCode 392. Is Subsequence in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official and forum solutions. A subsequence does not require consecutive characters, only that the order is preserved. For example, "ace" is a subsequence of "abcde", but "aec" is not because the order is violated.
