再帰的な二分法検索の使用

#include "stdio.h"

void Search(int p[],int low,int height,int key)
{
	int middle=(low+height)/2;
	if(low>height)
	{
		printf("    ！");
		return;
	}
	if(p[middle]==key)
	{
		printf("%d
",middle);
		return;
	}
	else if(p[middle]>key)
	{
		 Search(p,low,middle-1,key);
	}
	else if(p[middle]<key)
	{
		 Search(p,middle+1,height,key);
	}
}
int main()
{
	int p[5]={1,2,3,4,5};
	Search(p,0,4,4);
	return 0;
}
