注意特判奇数个数目为0的情况

#include<iostream>#include<cstdio>#include<cstring>#include<cstdlib>using namespace std;int main(){        char s[1005];        int a[30];        scanf("%s",s);              memset(a,0,sizeof(a));            int len=strlen(s);            for(int i=0;i<len;i++)                a[s[i]-'a']++;            int temp=0;            for(int i=0;i<26;i++)                if(a[i]%2==1)                temp++;            if(temp==0||temp%2==1)                cout<<"First"<<endl;            else                cout<<"Second"<<endl;    return 0;}
