Problem Statement
There are jewels, numbered to . The color of these jewels are represented by integers between and (inclusive), and the color of Jewel is . Also, these jewels have specified values, and the value of Jewel is .
Snuke would like to choose some of these jewels to exhibit. Here, the set of the chosen jewels must satisfy the following condition:
- For each chosen jewel, there is at least one more jewel of the same color that is chosen.
For each integer such that , determine if it is possible to choose exactly jewels, and if it is possible, find the maximum possible sum of the values of chosen jewels in that case.
Constraints
- For each of the colors, there are at least two jewels of that color.
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
Output
Print lines. In the -th line, if it is possible to choose exactly jewels, print the maximum possible sum of the values of chosen jewels in that case, and print otherwise.

We cannot choose exactly one jewel.
When choosing exactly two jewels, the total value is maximized when Jewel and are chosen.
When choosing exactly three jewels, the total value is maximized when Jewel and are chosen.
When choosing exactly four jewels, the total value is maximized when Jewel and are chosen.
When choosing exactly five jewels, the total value is maximized when Jewel and are chosen.
