从顺序表中删除其值在给定值s-t之间的所有元素

题目描述

从顺序表中删除其值在给定值s-t之间（包含s和t，要求s<t）的所有元素，若s或t不合理或顺序表为空，则显示错误信息并退出运行

#include<iostream>
using namespace std;
#define Maxsize 1000

typedef struct
{
	int data[Maxsize];
	int length;
}sqList;

bool del_s_t(sqList& L, int s, int t)
{
	int k = 0;
	if (L.length == 0 || s > t)
		return false;
	for (int i = 0; i < L.length; i++)
	{
		if (L.data[i] >= s && L.data[i] <= t)
		{
			k++;
		}
		else L.data[i - k] = L.data[i];
	}
	L.length -= k;
	return true;
}
int main()
{
	sqList L = {1,3,4,5,8,9,10};
	L.length = 7;
	cout << "init seq:";
	for (int i = 0; i < L.length; i++)
		cout << L.data[i] << " ";
	cout << endl;
	del_s_t(L, 2,5);
	cout << "changed seq:";
	for (int i = 0; i < L.length; i++)
		cout << L.data[i] << " ";
	return 0;
