47. Innovation workshop (algorithm ):Returns the longest descending subsequence of an array, for example, {9, 4, 3, 2, 5, 3, 2,4,3, 2} Idea: Dynamic Planning Calculates the longest descending subsequence of the sequence of the current number. Each time you look for the longest child sequence, scan the child sequence obtained before it, and the first number is smaller than the current number. For example, t
