codeforces 1060a（思维水题）

Let’s call a string a phone number if it has length 11 and fits the pattern “8xxxxxxxxxx”, where each “x” is replaced by a digit.

For example, “80123456789” and “80000000000” are phone numbers, while “8012345678” and “79000000000” are not.

You have n cards with digits, and you want to use them to make as many phone numbers as possible. Each card must be used in at most one phone number, and you don’t have to use all cards. The phone numbers do not necessarily have to be distinct.

Input
The first line contains an integer
n — the number of cards with digits that you have (1≤n≤100).

The second line contains a string of n digits (characters “0”, “1”, …, “9”) s1,s2,…,sn. The string will not contain any other characters, such as leading or trailing spaces.

Output
If at least one phone number can be made from these cards, output the maximum number of phone numbers that can be made. Otherwise, output 0.

0
Note
In the first example, one phone number, “8000000000”, can be made from these cards.

In the second example, you can make two phone numbers from the cards, for example, “80123456789” and “80123456789”.

In the third example you can’t make any phone number from the given cards.
完全就是一道思维水题，想明白就好了。。有可能有5个8，但是可能就只能组成两个电话号码。所以就只能是2。但是呢，如果可以组成5组电话号码，不过只有2个8，那也只能组成2个。找这之间的两者的最小值就好了。
代码如下：

#include
#include
#include
#include
#include
using namespace std;

int n;
char s[101];

int main()
{
	while(scanf("%d",&n)!=EOF)
	{
		int count=0;
		scanf("%s",s); 
		for(int i=0;i

多锻炼点思维，对a题有好处的。
努力加油a啊，(^o)/~
