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.

Deﬁnition 1. WebFeb 25, 2024 · So, a subsequence can be derived from another sequence by deleting some or none of the elements in between but always maintaining the relative order of elements in the original sequence. For example: {A, B, D} is one of the subsequences of the sequence {A, B, C, D, E} obtained after removing {C} and {E}.

WebWe will solve this problem using Dynamic Programming. Let dp[i] be the answer for the suffix of the array starting from i. We will calculate the dp from right to left. If a[i]≤0, then dp[i] = 0.
