JavaScript 中一个数位的乘积和差
问题
我们需要编写一个接受数字n的JavaScript函数。我们的函数应该找到该数字所有数字的总和与乘积之间的绝对差。
示例
以下是代码-
const num = 434312;
const sumProductDifference = (num = 1) => {
const sum = String(num)
.split('')
.reduce((acc, val) => acc + +val, 0);
const product = String(num)
.split('')
.reduce((acc, val) => acc * +val, 1);
const diff = product - sum;
return Math.abs(diff);
};
console.log(sumProductDifference(num));输出结果271
