Problem Description

As is known to all,the ASCII of character 'a' is 97. Now,find out how many character 'a' in a group of given numbers. Please note that the numbers here are given by 32 bits’ integers in the computer.That means,1digit represents 4 characters(one character is represented by 8 bits’ binary digits).

 

Input

The input contains a set of test data.The first number is one positive integer N (1≤N≤100),and then N positive integersai (1≤  ai≤2^32 - 1) follow

 

Output

Output one line,including an integer representing the number of 'a' in the group of given numbers.

 

Sample Input

3 97 24929 100

 

Sample Output

3

 

每次都被题意gank。。。好气呀！！！

题意：给出n个数，将这些数转化成2进制，然后对于每个数，每8位看成是一个数，看这个数是否是97，最后看有几个97。

模拟，算！ 注意不要用数组，会超时

#include
int main()
{
    int a,b[100],i,j,n;
    scanf("%d",&n);
    int ans=0;
    int tmp;
    for(i=0;i0)
        {
            b[pos++]=a%2;
            a/=2;
        }
        //b[pos]=0;
        tmp=0;
        for(j=1;j
