think like this, If the interval [s, e] can only be overwritten by one sprinkler, The subinterval [0, M] (s Because if [0, M] is completely overwritten, the [s, e] interval will be split, so we can mark the [s, e, One of the more convenient encoding methods is to directly mark the dp array with a special value. My approach is as follows: [Cpp]Dp [0] = 0;For (int I = 1; I For (int I = 0; I Int s, e;Scanf ("% d", s, e );For (int j = s + 1; j } Complete code:[Cpp]# Include # Include # Define L
