Re:But further observation reveals that only those indices in the set I = { l, k } ∪ { i : l < i < k ∧ opti > max i < j ≤ k { aj } } are worth considering.In Reply To:Re:But further observation reveals that only those indices in the set I = { l, k } ∪ { i : l < i < k ∧ opti > max i < j ≤ k { aj } } are worth considering. Posted by:Thank_you at 2007-12-29 13:54:20 来到k=6的时候l=4,k=6了,所以I={4,6},取4的话那么就是opt_3+a_4=10,取6就是opt_5+a_6=16,你挑一个吧 > 现在的解题报告改成您描述的那样的了。 > 但是这样的话(样例的前6个数字) > > n=6,m=17; > > idx 1 2 3 4 5 6 > opt 2 2 2 8 8 ? > arr 2 2 2 8 1 8 > > 这样前5个的opt求出来了,求第6个的时候,如果按照解题报告上的说法,是应该取第几个呢? > 实际上的情况应该是取第3个值的时候得到opt(6)=10吧。 > 所以还是不是很理解,劳烦st大哥了。 > Followed by:
