题目描述

Ricardo is a restaurant critic, which means he spends his time eating at restaurants and giving them a rating. Each rating is an integer number of stars between 00 and 33, inclusive. Thus, there are exactly four possible ratings.

During his visit to Cheapland, he must review NN restaurants. Unfortunately, all of them are terrible, and if left to his honest opinion, Ricardo would give 00 stars to every restaurant. However, the government of Cheapland can bribe Ricardo to increase the rating of any restaurant.

Each restaurant has its own bribe costs, which depend both on the restaurant itself and on the number of stars awarded. Bribing Ricardo to give a restaurant 33 stars is always more expensive than bribing him for 22 stars, which in turn is more expensive than bribing him for 11 star. Naturally, no payment is required for a 00-star rating.

As one might imagine, the Cheapland government wants to spend as little as possible while making their gastronomic scene look as strong as possible. To plan their strategy, they need to determine the minimum cost required to achieve a total of kk stars among all the NN restaurants, for every integer value kk between 11 and 3N3N, inclusive.

However, since bribe costs vary from restaurant to restaurant, calculating these values isn’t straightforward – which is why they need your help.

输入格式

The first line contains an integer NN (1N21051 \le N \le 2 \cdot 10^5) indicating the number of restaurants.

Each of the next NN lines describes a restaurant with three integers C1C_1, C2C_2 and C3C_3 (1C1<C2<C31091 \le C_1 < C_2 < C_3 \le 10^9), where CiC_i is the cost of getting a rating of ii stars for the restaurant.

输出格式

Output a line for each kk from 11 to 3N3N (inclusive), with an integer indicating the minimum total cost required to achieve exactly kk stars among all the NN restaurants.
