Description

编写一个函数来返回一个数字的阶乘。

一个数字的因子由下式给出：

N！ = n *（n-1）*（n-2）* ..... * 1

例如：3！ = 3 * 2 * 1 = 6 4！ = 4 * 3 * 2 * 1 = 24

注意：0！ = 1

Instructions

Tests

tests:
  - text: <code>factorial</code>是一种功能。
    testString: assert(typeof factorial === 'function');
  - text: <code>factorial(2)</code>应该返回一个数字。
    testString: assert(typeof factorial(2) === 'number');
  - text: <code>factorial(3)</code>应该返回6.“）
    testString: assert.equal(factorial(3), 6);
  - text: <code>factorial(3)</code>应返回120.“）
    testString: assert.equal(factorial(5), 120);
  - text: '<code>factorial(3)</code>应返回3,628,800。“）'
    testString: assert.equal(factorial(10), 3628800);
