Now, let's doDP. Letdp(i)dp(i)be the number of decreasing sequences (including the one with size 1) ending at position. Obviously:dp(i)=1+∑jaidp(j)dp(i)+∑jaidp(j). But that takes quadratic time. Let's optimize it some way. Let's keep an auxiliary arraycnt[], wherecnt[x...
Returntrueif you can splitnumsaccording to the above conditions, orfalseotherwise. A subsequence of an array is a new array that is formed from the original array by deleting some (can be none) of the elements without disturbing the relative positions of the remaining elements. (i.e.,[1,3...
