找出个数超过一般的数

#include<iostream>

using namespace std;

int findNum(int *number,int length){
	int currNum=0;
	int target;
	for(int i=0; i<length; i++){
		if(currNum==0){
			target=number[i];
			currNum=1;
		}
		else{
			if(number[i]==target)
				currNum++;
			else
				currNum--;
		}
	}
	return target;
} 


int main(){
	int num[10]={1,1,3,3,1,1,1,1,3,3};
	int target;
	target=findNum(num,10);
	cout<<target<<endl;
	return 0;
}
