http://codeforces.com/gym/100114 Description Integer sequences are very interesting mathematical objects. Let us examine a sequence generated with the use of two operations: doubling and “digit sorting”. The latter operation consists in ascending-order sort of the individual digits in the decimal...

但是,我们要求的是这些数合在一起,就像字符串拼接一样,一共有多少位。很简单,将不同位数的数的数量乘上它们各自的位数,就是一共的位数了。11 位:一共 99 个数,99 位。 22 位:一共 9090 个数,180180 位。 33 位:一共 900900 个数,27002700 位。 ……设位数为 lenlen,那么当前位数的数的总位数计算...
