下面程序实现插入排序算法。typedef struct{ int key; Info otherinfo;}SeqList;void InsertSort(SeqList R［］,int n){/* 待排序列保存在R［1..n］中*/SeqList x； int i，j，k，lo,hi,mi; for (i=2；i<=n；i++){ (1)；lo=1；hi=i-l; while (lo<=hi) { mi=(lo+hi)/2; if ((2)) break; if (R［mi］.key>x.key) hi=mi-l; else lo=mi+l;}if (mi=lo) k=i - mi;else k=i - mi-1;for (j=0；j(3)； R［i-j］=x；}}在空白处填写适当的内容，使该程序功能完整。(1)(2)(3)
