5900f3911000cf542c50fea4 | 问题37:可截断的素数 | 5 | problem-37-truncatable-primes |
--description--
3797号有一个有趣的财产。作为素数本身,可以从左到右连续删除数字,并在每个阶段保持素数:3797,797,97和7.同样,我们可以从右到左工作:3797,379,37和3。找到从左到右和从右到左都可截断的唯一n(8 <= n <= 11)个素数之和。注意:2,3,5和7不被认为是可截断的素数。
--hints--
truncatablePrimes(8)
应该返回1986年。
assert(truncatablePrimes(8) == 1986);
truncatablePrimes(9)
应该返回5123。
assert(truncatablePrimes(9) == 5123);
truncatablePrimes(10)
应该返回8920。
assert(truncatablePrimes(10) == 8920);
truncatablePrimes(11)
应该返回748317。
assert(truncatablePrimes(11) == 748317);
