--description--
十进制数,585 = 10010010012(二进制),在两个碱基中都是回文。找到所有数字的总和,小于n,而1000 <= n <= 1000000,它们在基数10和基数2中是回文的。(请注意,任一基数中的回文数可能不包括前导零。)
--hints--
doubleBasePalindromes(1000)
应该返回1772。
assert(doubleBasePalindromes(1000) == 1772);
doubleBasePalindromes(50000)
应该返回105795。
assert(doubleBasePalindromes(50000) == 105795);
doubleBasePalindromes(500000)
应该返回286602。
assert(doubleBasePalindromes(500000) == 286602);
doubleBasePalindromes(1000000)
应该返回872187。
assert(doubleBasePalindromes(1000000) == 872187);
