下列给定程序中，函数fun的功能是：把形参a所指数组中的最小值放在元素a[0]中，接着把a所指数组中的最大值放在a[1]元素中；再把a所指数组元素中的次小值放在a[2]中，把a所指数组元素中的次大值放在a[3]，依此类推。
规定fun函数中的max存放当前所找的最大值，px存放当前所找最大值的下标。
请在下画线处填入正确的内容并将下画线删除，使程序得出正确的结果。
注意：部分源程序给出如下。
不得增行或删行，也不得更改程序的结构！
试题程序：
# include ＜stdio.h＞
#define N 9
void fun (int a[], int n)
int i, j, max, min, px, pn, t;
for (i=0; i＜n-1; 1+=2)

/**********found********** /
max=min= (1) ;
px=pn=i;
for (j=i+1; j＜n; j++)
/**********found********** /
if (max ＜ (2) )
max=a[j]; px=j;
/**********found********** /
if (min＞ (3) )
min=a[j]; pn=j;

if (pn!=i)
t=a[il; a[i]=min; a[pn]=t;
if (px==i) px-pn;

if (px !=i+1)
t=a[i+1]; a[i+1]=max;
a[px]=t;

Insurance is the sharing of (1) . Nearly everyone is exposed (2) risk of some sort. The house owner, for example, knows that his (3) can be damaged by fire; the ship owner knows that his vessel may be lost at sea; the breadwinner knows that he may die by (4) and (5) his family in poverty. On the other hand, not every house is damaged by fire or every vessel lost at sea. If these persons each put a (6) stun of money into a pool, there will be enough to (7) the needs of the few who do suffer (8) . In other words the losses of the few are met from the contributions of the (9) . This is the basis of (10) . Those who pay the contributions are known as (11) and those who administer the pool of the contributions as insurer.
The (12) for an insurance naturally depends on how the risk is to happen as suggested (13) past experience. If the companies fix their premiums too (14) , there will be more competition in their branch of insurance and they may lose (15) . On the other hand, if they make the premiums too low, they will not have (16) and may even have to drop out (17) business. So the ordinary forces of supply and (18) keep premiums at a proper (19) to both insurers and those who (20) insurance.
