2.11－在顺序表va中插入x使仍然有序

typedef struct{int elem[max];int length;}Seqlist;void insert(Seqlist &va,int x){int flag,i,j;if(va.elem[va.length-1]-va.elem[0]>=0)flag=1;else flag=-1;for(i=0;i<va.length;i++){if(flag*((va.elem[i])-x)>=0){for(j=va.length;j>i;j--){va.elem[j]=va.elem[j-1];}va.elem[i]=x;return;}}va.elem[va.length]=x;}
