吧里计算机专业的同学帮帮忙啊

要写实验原理（算法描述：自然语言、流程图、伪代码三选一）

# 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; i+=2)
{
/**********found**********/
max = min = a[i];
px = pn = i;
for (j=i+1; j<n; j++) {
/**********found**********/
if (max<a[j])
{ max = a[j]; px = j; }
/**********found**********/
if (min>a[j])
{ min = a[j]; pn = j; }
}
if (pn != i)
{ t = a[i]; 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; }
}
}
main()
{ int b[N]={9,1,4,2,3,6,5,8,7}, i;
printf("\nThe original data :\n");
for (i=0; i<N; i++) printf("%4d ", b[i]);
printf("\n");
fun(b, N);
printf("\nThe data after moving :\n");
for (i=0; i<N; i++) printf("%4d ", b[i]);
printf("\n");

第二题
#include <stdio.h>
long fun(int g)
{
/**********found**********/
switch(g)
{ case 0: return 0;
/**********found**********/
case 1 :case 2 :return 1 ;
}
return( fun(g-1)+fun(g-2) );
}
main()
{ long fib; int n;
printf("Input n: "); scanf("%d",&n); printf("n = %d\n",n);
fib=fun(n);
printf("fib = %d\n\n",fib);
}
