## Description
|
||
<section id="description"><p> Ackermann函数是递归函数的典型示例，尤其值得注意的是它不是原始递归函数。它的值增长非常快，其调用树的大小也是如此。 </p><p> Ackermann函数通常定义如下： </p> $$ A（m，n）= \ begin {cases} n + 1＆\ mbox {if} m = 0 \\ A（m-1,1）＆\ mbox {if} m> 0 \ mbox {和} n = 0 \\ A（m-1，A（m，n-1））＆\ mbox {if} m> 0 \ mbox {和} n> 0. \ end {cases} $$ <p>它的论点永远不会消极，它总是终止。编写一个返回$ A（m，n）$的值的函数。任意精度是首选（因为函数增长如此之快），但不是必需的。 </p></section>
