codeforces 1006c

本文介绍了一种将数字序列分为三组并使首尾两组和相等且总和最大的算法实现。通过从两端开始逐步加和并调整以保持平衡,确保得到最优解。

题目大意是把一串数字分三部分,第一部分和和第三部分和相等,并让和尽可能的大

思路就是·两边开始加,谁小谁多加一个,直到两边和相同,记录下来,然后继续加加到数字重复为止

懒着判断该进行到哪里结束,就把加过的全都归零了

ac代码

#include <stdio.h>
int main()
{
    int n;
    scanf("%d",&n);
    long long out1=0,out2=0;
    int number[n];
    int i,j;
    for(i=0;i<n;i++)
    {
        scanf("%d",&number[i]);
    }
    out1=number[0];
    number[0]=0;
    out2=number[n-1];
    number[n-1]=0;
    i=1;
    j=n-2;
    long long out=0;
    while(i<j+5)
    {
        if(out1<out2)
        {
            out1+=number[i];
            number[i]=0;
            i++;
        }
        if(out1>out2)
        {
            out2+=number[j];
            number[j]=0;
            j--;
        }
        if(out1==out2)
        {
            out=out1;
            out1+=number[i];
            number[i]=0;
            i++;
        }
    }
    printf("%lld\n",out);
    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)) ```
