Currently, in ABC, some users use generative AI to solve problems, which has slightly diminished the competitiveness and reduced the reliability of ratings. It is very difficult to completely separate generative AI from the current programming environment, and it should not be entirely banned. However, merely using generative AI to solve problems is neither valuable as ...
Jan 6, 2019 · Problem Statement. There are N stones, numbered 1, 2, \ldots, N. For each i (1 \leq i \leq N), the height of Stone i is h_i. There is a frog who is initially on Stone 1. He will repeat the following action some number of times to reach Stone N: If the frog is currently on Stone i, jump to Stone i + 1 or Stone i + 2.

Jan 6, 2019 · Problem Statement. There are N N items, numbered 1, 2, \ldots, N 1,2,…,N. For each i i (1 \leq i \leq N 1 ≤ i ≤ N), Item i i has a weight of w_i wi and a value of v_i vi. Taro has decided to choose some of the N N items and carry them home in a knapsack.
This problem can be solved with Dynamic Programming, or DP. DP is an algorithm of solving from smaller-sized subproblems to larger ones, and when solving a larger-sized one it uses the result of the smaller-sized ones.
