OJ输入练习（JS 版）

写这一篇的目的是因为我没有参加算法比赛的经验，平常练习也是在 `LeetCode` 上，使用都是核心代码模式。

其实现在想想还挺简单的。

系统输入的是一个字符串，那我们需要的可能是其中的数字，所以第一步就是需要对字符串进行切割成为字符串数组，第二步就是对其中的每一个元素使用 `parseInt` 做数字转换处理。

最好的是我们封装一个函数，这样将取到的参数传入其中。如此，就可以像使用核心代码模式一样编写了。

let line = ''
    
    let solveFunc = function(num1, num2) { 
        return num1 + num2;
    }
    
    while(line = readline()) { 
        let [num1, num2] = line.split(' ').map(i => parseInt(i));
        let result = solveFunc(num1, num2);
        print(result)
    }

    let solveFunc = function(num1, num2) { 
        return num1 + num2;

    while(line = readline()) { 
        let [num1, num2] = line.split(' ').map(i => parseInt(i));
        let result = solveFunc(num1, num2);
        print(result)
