最基本的思路

这也可以
#include <stdio.h>
void sort( int arr[],int n)
{
	 int max = arr[0];
	for (int i = 0; i < n; i++)
	{
		if (arr[i] > max)
			max = arr[i];
	}
	 int t = 0;
	for (int i = 0; i < n; i++)
	{
		if (arr[i] == max)
		{
			continue;
		}
		t += arr[i];
	}
	printf("%d", t);
}
int main()
{
	int n;
	 int arr[100] = { 0 };
	scanf("%d", &n);
	for (int i = 0; i < n; i++)
	{
		scanf("%d", &arr[i]);
	}
	sort(arr,n);
	return 0;
}
