POJ 1952 buy low, buy lower dp records data The longest descending subsequence is added to record the number of longest descending subsequences, and then deduplication is required. The most troublesome thing is to remove duplicates. The basic idea is: duplicate values are displayed in all cases, and then sub-sequences of the same length exist.

It is also a simple Minimum Spanning Tree Algorithm. However, some new things need to be added, which requires a deep understanding of the Minimum Spanning Tree Algorithm and the use of the query set. The solution to the problem is also complicated. #include The subset enumeration algorithm is required for the given solutions. In the preceding solution, the binary help subset enumeration method is used, which is only applicable to the subset enumeration algorithm with small set elements. The a

If she had no class today, she would accompany Huang Bo to guicheng to help Tom with things. At this time, she did not know what the situation was like. In the car, I accidentally saw a "jetant" Bicycle monopoly, and told Huang Bo that he liked all the people who went to Singapore. recently he was quite depressed. Haha, I want to learn from him. The Moho in guicheng is really tnnd expensive, and it costs 3 yuan for two kilometers. How can I not step on a bicycle ?! When I came back, I went th

The longest descending subsequence is added to record the number of longest descending subsequences, and then deduplication is required. The most troublesome thing is to remove duplicates. The basic idea is: duplicate values are displayed in all cases, and then sub-sequences of the same length exist. Here, the sub-sequence of the DP Record ends with the current value, and you must select the longest descending subsequence of this value, then you need to subtract the subsequence that already exis
