第四题 阅读以下说明、C函数和问题，回答问题1和问题2将解答填入答题纸的对应栏内。
【说明】
当数组中的元素已经排列有序时，可以采用折半查找（二分查找）法查找一个元素。下面的函数biSearch(int r[]，int low，int high，int key)用非递归方式在数组r中进行二分查找，函数biSearch_rec(int r[]，int low，int high，int key)采用递归方式在数组r中进行二分查找，函数的返回值都为所找到元素的下标；若找不到，则返回-1。
【C函数1】
int biSearch(int r[]，int low，int high，int key)
//r[low..high] 中的元素按非递减顺序排列
//用二分查找法在数组r中查找与key相同的元素
//若找到则返回该元素在数组r的下标，否则返回-1
{
int mid;
while(（1）) {
mid = (low+high)/2 ;
if (key ==r[mid])
return mid;
else if (key （2）;
else
（3）;
}/*while*/
return -1;
}/*biSearch*/
【C 函数 2】
int biSearch_rec(int r[]，int low，int high，int key)
//r[low..high]中的元素按非递减顺序排列
//用二分查找法在数组r中查找与key相同的元素
//若找到则返回该元素在数组r的下标，否则返回-1
{
int mid;
if(（4）) {
mid = (low+high)/2 ;
if (key ==r[mid])
return mid;
else if (key return biSearch_rec(（5）,key);
else
return biSearch_rec(（6）,key);
}/*if*/
return -1;
}/*biSearch_rec*/ 问题：4.1 (12分）
