, section 15-4. Its thought is worth drawing on. It is instructive to deal with these "irregular" sub-string problems, and for the longest common subsequence, not the longest common subsequence of the continuity that we used to be familiar with, but the common subsequence that does not require continuity, so we know we cannot start indenting or Backoff from two subsequence.This is the characteristic of these problems. The palindrome for this problem is that we use similar ideas, if equal, then g
