[STL训练]美国大选-题解（C语言代码）

怎么做到想法一样的
#include <stdio.h>
int main()
{
	int n, arr[100] = {0};
	while (scanf("%d", &n)!=EOF)
	{
		if (n == 0)
			break;
		for (int i = 0; i < n; i++)
		{
			scanf("%d", &arr[i]);
		}
		for (int i = 0; i < n; i++)
		{
			for (int j = 0; j < n - i - 1; j++)
			{
				if (arr[j] > arr[j + 1])
				{
					int t = arr[j];
					arr[j] = arr[j + 1];
					arr[j + 1] = t;
				}
			}
		}
		int sum = 0;
		for (int i = 0; i < n / 2 + 1; i++)
		{
			sum += arr[i] / 2 + 1;
		}
		printf("%d\n", sum);
	}
	return 0;
}
