01 A complete backpack problem.
This mainly describes the number of combinations. There are more people doing two-dimensional DP. here we can use one-dimensional DP.
One-dimensional transformation equation: DP [J] = DP [J-I] + dp [J]; where I represents the weight and J represents the current backpack capacity.
This means that DP [J-I] indicates the maximum combination of J-I backpack weights. If the size of the backpack is J, that is, you can pack the I-th item into a backpack, so there is a D
Simple recursion (recursive statements do not want to be written), but they must be highly precise.
The result is not 1A... Thank you...
To write high precision, suddenly think of Pascal's advanced features, which can define operator, write class, and bring the unit avltree !!!

equation is a little different.Equation d[i][j]--The number of integers I, the largest integer in the division is less than JThus the classification is discussed, if I, the division of Integer I, the largest integer must be less than or equal to I, so d[i][j] = D[i][i].If i = j, the division of Integer I, the individual i is a division, so, the division of Integer I can be divided into a separate I and no I division, then d[i][j] = d[i][j-1]+1If I > J, the division of Integer I can be divided i
]: Indicates how many combinations of J coins are available when calculating the current I item.Then state conversion: dp[i][j] = Dp[i-1][j] + Dp[i][j-i]//dp[i-1][j] represents the number of combinations calculated for the previous item, that is, the number of combinations that do not buy I items, Dp[i][j-i] Indicates the number of combinations of I items that are vacated I coinsDifficulties:If you look closely, you will find that not only the two-dimensional arrays are not used, but even scroll
