Factorial with recursion
WebRecursion. Recursion is the technique of making a function call itself. This technique provides a way to break complicated problems down into simple problems which are easier to solve. Recursion may be a bit difficult to understand. The best way to figure out how it works is to experiment with it. Web上次调用 factorial ，其中 x 为2。这反过来会将2*1返回到对 factorial 的上一次调用，其中 x 是3。这就得到了3*2，将结果-6-返回给函数的第一次调用。
