建立26个小写字母的顺序表，在该顺序表k=6处插入字符“＄”，并显示出来。然后再删除k=12处的字母，并显示删除后的结果。

struct SqList {
	int* elem;
	int length;
	int listsize;
};
int InitList_Sq(SqList& L) {	//构造空表
	L.elem = 0;
	L.length = 0;
	L.listsize = 0;
	return 1;
}

int InsertList_Sq(SqList& L, int i, int x) {	//在第i个位置插入x
	if (L.listsize == 0) {
		L.elem = new int[1];
		L.listsize = 1;
	}
	if (i<0 || i>L.length) return 0;
	if (L.length == L.listsize) {
		int* newbase = new int[L.listsize * 2];
		if (newbase == 0) return 0;
		for (int j = 0; j < L.length; ++j) {
			newbase[j] = L.elem[j];
		}
		delete L.elem;

	L.length++;
	return 1;
