WebApr 2, 2024 · The first reason is that the base subproblem is one of two options. When we need to calculate the answer to a range of length 1, its answer equals to one. That’s because any sequence of length one is a palindrome. Otherwise, if we reach an empty range, the answer to it is just zero. WebThe subsequence ( a k ′) k ≥ 1 defined by a k ′ := a n k ( k ≥ 1) is bounded, therefore it has a subsequence ( a l ″) l ≥ 1 converging to some α ∈ R. This sequence ( a l ″) l ≥ 1 can be considered as a subsequence of the originally given sequence ( a n) n ≥ 1. Share Cite Follow answered Jul 4, 2013 at 16:12 Christian Blatter 221k 13 175 440
