//还没开始做，这次的时限只有2000分钟，明天要出去玩，今天先存一下以免过期了看不到了。
先写一个过了再说，想到了再来写。

#include 
void method1(int [],int);
void method2(int [],int);
void method3(int [],int);
void method4(int [],int);
int main(int argc, char const *argv[])
{
	int a[5],i,k;
	for(i=0;i<5;i++) scanf("%d",&a[i]);
	method1(a,5);
	for(i=1;i<=4;i++)
		{
			printf("METHOD %d\n",i);
			for(k=0;k<5;k++)
				printf("%d%c",a[k],k==4?'\n':' ');
		}
	return 0;
}

void method1(int a[],int n)
{
	int i,tmp;
	for(i=0;i<=n/2;i++)
	{
		tmp=a[i];
		a[i]=a[n-i-1];
		a[n-i-1]=tmp;
	}
}
//Exchange head and tail
