problem number 1well err?.. i don't like to ask for help with homeworks but i really don't know how to solve this problem..
At the new year's eve concert the first 2 rows are reserved to the officials. Both rows are formed from the same number of chairs S. The chairs are numbered from 1 to S, from left to right. There are N official persons who must receive an invitation (let's count them from 1 to N). Each official person comes with a group. let's note with Gi the number of members from i's group (including i, the official). The members of a group must be placed on the same row on consecutive places, or (if the number of members is even) the members of the group can be divided into 2 halves and they can be placed on consecutive places having the same numbers on the 2 rows. Write a program which determines the minimum value of S which forms the 2 rows to arrange all members from the groups according to the rules. Input data file in.txt contains on the first line the number N of official persons. on the second line there are N numbers separated by a space = G1, G2 ... Gn where Gi represents the number of members from i's group. (including i) Output data write the minimum value of S.. wherever you want... 1<=N<=1000 G1+G2+...+GN<=100000 Example: file in.txt 4 20 5 3 1 output: 15 |

Re: problem number 1OK, so the example data has the groups (let's label them as A B C D) seated as:
Code:
`AAAAAAAAAABBBBB` The next step would be to see if you can fit the people into that many seats. If you can, then you have a solution. If not, then increase the number of seats by 1 and try again. The tricky bit is going to be assigning the seats. You don't have to find the optimal packing; the rest of the algorithm will take care of that, so you only need to know if it is possible. |
