Problem Description
“OK, you are not too bad, em… But you can never pass the next test.” feng5166 says.
“I will tell you an odd number N, and then N integers. There will be a special integer among them, you have to tell me which integer is the special one after I tell you all the integers.” feng5166 says.
“But what is the characteristic of the special integer?” Ignatius asks.
“The integer will appear at least (N+1)/2 times. If you can’t find the right integer, I will kill the Princess, and you will be my dinner, too. Hahahaha…..” feng5166 says.
Can you find the special integer for Ignatius?

简单题,主要要理解题意 (N+1)/2 这个条件很关键。
#include<algorithm> #include<iostream> #include<cstdio> #include<cstring> using namespace std; int main() { int a,b,num,t; while(scanf("%d",&t)!=EOF) { scanf("%d",&a); num=1; for(int i=1;i<t;i++) { scanf("%d",&b); if(a==b) num++; else if(--num==0) a=b,num++; } printf("%d\n",a); } return 0; }
