[编程题]1016. 部分A+B (15)

热度指数：29521 时间限制：C/C++ 1秒，其他语言2秒空间限制：C/C++ 32M，其他语言64M
算法知识视频讲解

正整数A的“D_A（为1位整数）部分”定义为由A中所有D_A组成的新整数P_A。例如：给定A = 3862767，D_A = 6，则A的“6部分”P_A是66，因为A中有2个6。

现给定A、D_A、B、D_B，请编写程序计算P_A + P_B。

输入描述:

输入在一行中依次给出A、D_A、B、D_B，中间以空格分隔，其中0 < A, B < 10¹⁰。

输出描述:

在一行中输出P_A + P_B的值。

分析

$10^{10}=100亿$ ，int正数最大为20亿左右，所以不能用int，需要long long类型。

啥

总体思路：

写一个提取函数。如下代码：
提取两对数，相加。

代码如下：

#include <iostream>

using namespace std;

int extractNum(int A, int DA);

int main()
{
    int A, DA, B, DB;
    cin >> A >> DA >> B >> DB;
    int PA, PB;
    PA = extractNum(A, DA);
    PB = extractNum(B, DB);
    cout << PA + PB << endl;
    return 0;
}

int extractNum(int A, int DA)
{
    int res = 0;
    while(A>0) {
        int temp = A%10;
        if(temp == DA) {
            res = res*10 + DA;
        }
        A /= 10;
    }
    return res;
}

JavaScript

八千鸟

核心代码一行，js的思路

用正则将数据A中的非Da替换掉，然后数字化。同样处理B之后，相加就可以了

var readline = require('readline');
const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout,
    terminal: false
});
rl.on('line', function(line) {
    var arr = line.split(' ');
    console.log((+arr[0].replace(new RegExp("[^" + arr[1] + "]", 'g'), '')) + (+arr[2].replace(new RegExp("[^" + arr[3] + "]", 'g'), '')));
});
