Question: The weight (IQ) of up to 1000 elephants may be the same, and the weight may be the same, the length and sequence of the strictly decreasing IQ are output. The sequence is represented by the serial number in the input data.
Idea: Step 1: sort these elephants by weight. During sorting, you only need to sort the indexes. You do not need to change the actual data of the elephants, such as (600,300,400 ), the corresponding index
The attributes of n elephants, including weight w and IQ s, are given. Now we need to find a continuous sequence, requiring each elephant to have a higher weight than the previous one, the IQ is small, and the maximum value and solution are output. If the solution is not unique, either of them is output. Solution: The longest
