https://leetcode.com/problems/is-subsequence/ Given two strings s and t, return true if s is a subsequence of t, or false otherwise. 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).

| - while elseを使う（なんとなく聞いたことあるくらいで、よく把握していないので調べた） これは全然慣れない。結局コードを参照しながら書いて時間がかかった。慣れといた方がいいのか？ |

私も、Python native じゃないので、while else 慣れない(し自然さは感覚がない)んですが、CPython のコードなどを見ていると、たまに出てきますね。

コード例ありがとうございます。
見てみましたが、自分にとっては複雑でまだ処理が終えてないのでまた時間がある時に見てみます
