Codeforces Round #748 (Div. 3) D1. All are Same 读题 由题意知道,最终只能减到0。那么可将最小值代表为0,其他值减去最小值。接下来获取最大的k,k满足能将每个数减到0。 场上思路 既然k可能成立,也可能不成立,那么可以从a[i]的范围出发进行二分,如果这个k能成立,那么就贪心的向大走。 反思 场上思路没有考
容易发现减去的最大值是差值的最大公约数,而algorithm中的__gcd(a,b)可求a与b的最大公约数,且在b=0时输出a,可解决此问题。 View Code
范围内的立方体木块。你每次能在这个网格图中选择一个位置加上 个立方体木块,或者选择两个相邻位置各加上 因为不论怎么操作,都是给现有的方块堆加上 个方块,因此奇偶性不变。我们假设初始最高的一堆木块高度为 ,如果最终能够使得所有位置高度一致,则需要满足: ,其中 指代网格图中位置为 不难发现如果 为奇数,则...
States on the right are obtained by performing one of the above operations on the state on the left, and grey cubes are added due to the operation.Player's goal is to make the height of all cells the same (i.e. so that each cell has the same number of cubes in it) using above ...
and all the following problems up to F took him less than 8 minutes each. The second one made parcels via E at the end of the round; his comment code contained half of the total volume. At the same time, his code passed first 0 tests and then 1, but was still unable to pass all...
time. Find the cycle created by the edge, and contract the entire cycle into one vertex. Repeat for the entire Dijkstra run. This should take the same total time complexity with Dijkstra. The edges in the shortest path of the final graph are the ones in the intersection of all shortest ...
"DeepSeek makes the same mistakes O1 makes, a strong indication the technology was ripped off," billionaire investor Vinod Khosla said on X, without giving more details. It's a claim that OpenAI itself has alluded to, telling CNBC in a statement Wednesday that it is reviewing repo...
I mainly need to figure out how to test if an interval is of the same number. There are multiple ways to do it, but intuitively we can run a prefix sum onA[i] == A[i - 1]. Now the problem looks codeable to me. Implementation ...
Note: Best results are shown in bold. Scores with a gap not exceeding 0.3 are considered to be at the same level. DeepSeek-V3 achieves the best performance on most benchmarks, especially on math and code tasks. For more evaluation details, please check our paper. Context Window Evaluation...
