个人练习-PAT甲级-1113 Integer Set Partition

题目链接https://pintia.cn/problem-sets/994805342720868352/problems/994805357258326016

不懂为什么是25分的题。。。

思路：对半分，奇数的话大的那个set多一个数。然后排序，前一半给小set，后一半给大set。最后输出即可

int main() {
    int N;
    scanf("%d", &N);
    vector<int> arr(N);
    for (int i = 0; i < N; i++) {
        scanf("%d", &arr[i]);
    }

    int n1 = N/2, n2 = N/2;
    if (N % 2 != 0)
        n2++;

    sort(arr.begin(), arr.end());

    int s1 = 0, s2 = 0;
    for (int i = 0; i < n1; i++)
        s1 += arr[i];
    for (int i = n1; i < N; i++)
        s2 += arr[i];

    printf("%d %d", n2-n1, s2-s1);


    return 0;
