Description
You want to arrange the window of your flower shop in a most pleasant way. you have f bunches of flowers, each being of a different kind, and at least as your vases ordered in a row. the vases are glued onto the shelf and are numbered consecutively 1 through V, where V is the number of vases, from left to right so that the vase 1 is the leftmost, and the vase V is the rightmost vase. the bunches are moveable and are uniquely identified by integers between 1 and F. these IDnumbers have a significance: they determine the required order of appearance of the flower bunches in the row of vases so that the bunch I must be in a vase to the left of the vase containing bunch J whenever I <j. suppose, for example, you have bunch of azaleas (IDnumber = 1), a bunch of begonias (IDnumber = 2) and a bunch of carnations (IDnumber = 3 ). now, all the bunches must be put into the vases keeping their IDnumbers in order. the bunch of Azaleas must be in a vase to the left of IAS Onias, and the bunch of begonias must be in a vase to the left of carnations. if there are more vases than bunches of flowers then the excess will be left empty. A vase can hold only one bunch of flowers.
Each vase has a distinct characteristic (just like flowers do ). hence, putting a bunch of flowers in a vase results in a certain aesthetic value, expressed by an integer. the aesthetic values are presented in a table as shown below. leaving a vase empty has an aesthetic value of 0.

According to the table, azaleas, for example, wocould look great in vase 2, but they wowould look awful in vase 4.
To achieve the most pleasant effect you have to maximize the sum of aesthetic values for the arrangement while keeping the required ordering of the flowers. if more than one arrangement has the maximal sum value, any one of them will be acceptable. you have to produce exactly one arrangement.
Input
 The first line contains two numbers:F,V.
 The followingFLines: Each of these lines containsVIntegers, so thatAIJIs given asJthNumber on (I+ 1)StLine of the input file.
 1 <= F <= 100 where F is the number of the bunches of flowers. The bunches are numbered 1 through F.
 F <= V <= 100 where V is the number of vases.
 50 <= AIJ <= 50 where AIJ is the aesthetic value obtained by putting the flower bunch I into the vase J.
Output
The first line will contain in the sum of aesthetic values for your arrangement.

Question:
F flowers are placed in V bottles, and each flower has a corresponding ornamental value in each bottle. One bottle can only hold one flower and the biggest ornamental value is obtained.
Use DP [I] [J] to represent the maximum ornamental value of an I flower placed in the J bottles. The state transition equation is available:
DP [I] [J] = DP [I] [J1]> DP [I1] [J1] + A [I] [J]? DP [I] [J1]: DP [I1] [J1] + A [I] [J];
Code:
# Include <iostream>
# Include <cstring>
Using namespace STD;
Int main (){
Int F, V, I, J;
Int A [110] [110];
Int DP [110] [110];
While (CIN> F> V ){
For (I = 1; I <= f; I ++)
For (j = 1; j <= V; j ++)
Cin> A [I] [J];
Memset (DP, 0, sizeof (DP ));
DP [1] [1] = A [1] [1];
For (I = 2; I <= f; I ++)
DP [1] [I] = DP [1] [I1]> A [1] [I]? DP [1] [I1]: A [1] [I];
For (I = 1; I <= f; I ++ ){
DP [I] [I] = DP [I1] [I1] + A [I] [I];
For (j = I + 1; j <= V; j ++)
DP [I] [J] = DP [I] [J1]> DP [I1] [J1] + A [I] [J]? DP [I] [J1]: DP [I1] [J1] + A [I] [J];
}
Cout <DP [f] [v] <Endl;
}
Return 0;
