Excel表列名称由字母A~Z组成，列字母的规律如下: A、B、C.、AA、AB....AZ、BA、B...ZZZZY、ZZZZ...输入: 输入包含两个列名称字符串，长度均小于等于5。 输出: 输出两个列名称之间共有多少列

样例输入:

AA  AZ

样例输出:

24

代码：

C++：

#include<iostream>
#include<string>
#include<cmath>
using namespace std;
int main() {
	string s1; cin >> s1;
	string s2; cin >> s2;
	int n1 = 0, n2 = 0;
	for (int i = 0; i < s1.length(); i++) {
		n1 *= 26;
		n1 += s1[i] - 'A' + 1;
	}
	for (int i = 0; i < s2.length(); i++) {
		n2 *= 26;
		n2 += s2[i] - 'A' + 1;
	}
	cout << n1 << endl;
	int res1 = max(n1, n2);
	int res2 = min(n1, n2);
	cout << res1 - res2 - 1 << endl;
	return 0;
}

Python：

class Solution:
    def main(self):
        s1 = input()
        s2 = input()
        n1 = 0
        n2 = 0
        for i in s1:
            n1 *= 26
            n1 += ord(i) - 16 + 1
        for i in s2:
            n2 *= 26
            n2 += ord(i) - 16 + 1
        print(abs(n1 - n2))
if __name__=="__main__":
    s = Solution()
    s.main()

Java：

package com.my.gududu;

import java.util.*;


public class Main {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        String s1 = input.nextLine();
        String s2 = input.nextLine();
        int n1 = 0, n2 = 0;
        for (int i = 0; i < s1.length(); i++) {
            n1 *= 26;
            n1 += s1.charAt(i) - 'A' + 1;
        }
        for (int i = 0; i < s2.length(); i++) {
            n2 *= 26;
            n2 += s2.charAt(i) - 'A' + 1;
        }
        System.out.println(Math.abs(n1 - n2));
    }
}
