codeforces 703C

题目链接:http://codeforces.com/contest/703/problem/C

思路:分三种情况:

①. 人在走到各顶点对应纵坐标时车均在右侧,即均未到达。

② .人在走到各顶点对应纵坐标时车均在左侧,即均已驶过。

③. 左右两侧均有分布。

对于①②,人可以直接以最快速度行走至终点,即w / u。

对于③,找出相对人最晚到达的车,人必须在0 ~ y 之间进行速度调整,但时间都是t = x / v。

using namespace std;
typedef long long ll;
int main()
{
    int n,w,x,y;
    double v,u,minx=10000,maxx=-10000;
    int flagx,flagy;
    scanf("%d%d%lf%lf",&n,&w,&v,&u);
    while(n--)
    {
        scanf("%d%d",&x,&y);
        if(y/u-x/v<minx)
        {
            flagx=x;
            flagy=y;
            minx=y/u-x/v;
        }
        maxx=max(maxx,y/u-x/v);
    }
    if(maxx<=0||minx>=0)
        printf("%.10lf\n",w/u);
    else
        printf("%.10lf\n",flagx/v+(w-flagy)/u);
    return 0;
}


### Codeforces Problem 1332C Explanation The provided references pertain specifically to problem 742B on Codeforces rather than problem 1332C. For an accurate understanding and solution approach for problem 1332C, it's essential to refer directly to its description and constraints. However, based on general knowledge regarding competitive programming problems found on platforms like Codeforces: Problem 1332C typically involves algorithmic challenges that require efficient data structures or algorithms such as dynamic programming, graph theory, greedy algorithms, etc., depending upon the specific nature of the task described within this particular question[^6]. To provide a detailed explanation or demonstration concerning **Codeforces problem 1332C**, one would need direct access to the exact statement associated with this challenge since different tasks demand tailored strategies addressing their unique requirements. For obtaining precise details about problem 1332C including any sample inputs/outputs along with explanations or solutions, visiting the official Codeforces website and navigating to contest number 1332 followed by examining section C is recommended. ```python # Example pseudo-code structure often seen in solving competitive coding questions. def solve_problem_1332C(input_data): # Placeholder function body; actual logic depends heavily on the specifics of problem 1332C. processed_result = process_input(input_data) final_answer = compute_solution(processed_result) return final_answer input_example = "Example Input" print(solve_problem_1332C(input_example)) ```
