角谷猜想的内容是：任意一个自然数，若为偶数除以2，若为奇数则乘3加1，得到一个新的自然数后按照上面的法则继续演算，若干次后得到的结果必然为1。编程验证该定理。-Kakutani conjecture content is: an arbitrary natural number, if it is even divided by 2, if it is odd then multiply three plus one, get a new natural number and follow the above rules continue calculations, the results obtained after several inevitable for one. Programming validate the theorem.
