第三十一题

已知2条地铁线路,其中A为环线,B为东西向线路,线路都是双向的。经过的站点名分别如下,两条线交叉的换乘点用T1、T2表示。编写程序,任意输入两个站点名称,输出乘坐地铁最少需要经过的车站数量(含输入的起点和终点,换乘站点只计算一次)。

地铁线A(环线)经过车站:A1 A2 A3 A4 A5 A6 A7 A8 A9 T1 A10 A11 A12 A13 T2 A14 A15 A16 A17 A18

地铁线B(直线)经过车站:B1 B2 B3 B4 B5 T1 B6 B7 B8 B9 B10 T2 B11 B12 B13 B14 B15

第三十二题

32.输入一串数,以’,’分隔,输出所有数中去掉最大值、最小值之后剩下的个数。(其中最大值与最小值可能有多个)

Smple input:3,3,5,3,6,9,7,9 Sample outPut: 3

#include <iostream>
#include <string>
#include <vector>
using namespace std;

int residualNum(const string &s){
vector<int> v;
auto begin = s.begin();
while (begin != s.end())
{
auto ahead = begin + 1;
while (ahead != s.end() && *ahead != ',')
{
ahead++;
}
string tmp(begin, ahead);
v.push_back(stoi(tmp));
if (ahead == s.end()) break;
begin = ++ahead;
}

int min = v[0], max = v[0], minCount = 1, maxCount = 1;
for (int i = 1; i < v.size(); i++)
{
if (v[i] < min){
min = v[i];
minCount = 1;
}
else if (v[i] == min)
{
minCount++;
}

if (v[i] > max){
max = v[i];
maxCount = 1;
}
else if (v[i] == max)
{
maxCount++;
}
}

return v.size() - minCount - maxCount;
}

int main()
{
string s;
cin >> s;
cout << residualNum(s) << endl;
return 0;
}


第三十三题

33.要从5个人中选取2个人作为礼仪,其中每个人的身高范围为160-190,要求2个人的身高差值最小(如果差值相同的话,选取其中最高的两人),以升序输出两个人的身高。

Smple input:161 189 167 172 188 Sample outPut: 188 189

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

void selectMan(vector<int> &v, int &i1, int &i2){

sort(v.begin(),v.end());
int min = v[1] - v[0], index = 0;
for (unsigned i = 1; i < v.size()-1; i++)
{
if (v[i+1] - v[i] <= min)
{
min = v[i+1] - v[i];
index = i;
}
}
i1 = v[index];
i2 = v[index+1];
}

int main()
{
vector<int> v;
for (int i = 0; i < 5; i++)
{
int num;
cin >> num;
v.push_back(num);
}
int i1,i2;
selectMan(v,i1,i2);
cout << i1 << " " << i2 << endl;
return 0;
}


第三十四题

34.输入一串字符串,其中有普通的字符与括号组成(包括‘(’、‘)’、‘[’,’]’),要求验证括号是否匹配,如果匹配则输出0、否则输出1.

#include <iostream>
#include <string>
#include <stack>
using namespace std;

bool isMatch(const string &s){
stack<char> charStack;
for (auto begin = s.begin();begin != s.end();++begin){

{
charStack.push(*begin);
continue;
}
if (*begin == ')')
{
if (!charStack.empty() && charStack.top() == '(')
{
charStack.pop();
continue;
}
return false;
}
if (*begin == ']')
{
if (!charStack.empty() && charStack.top() == '[')
{
charStack.pop();
continue;
}
return false;

charStack.pop();
continue;

第三十五题

35.判断回文数,是返回1,不是返回0。

#include <iostream>
#include <vector>
using namespace std;

bool isPalindrome(int n){
vector<int> v;
while (n != 0)
{
v.push_back(n%10);
n /= 10;
}

for (unsigned i = 0; i < v.size()/2; i++)
{
if (v[i] != v[v.size()-i-1])
{
return false;
}
}
return true;
}

int main()
{
int n;
cin >> n;
cout << isPalindrome(n) << endl;
return 0;
}
