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...
Digits Sequence Dividing time limit per tes 1 second memory limit per test 256 megabytes 题目链接http://codeforces.com/problemset/problem/1107/A 题目大意:给你n个询问,问你是否能将一个数分成n段,对于每段i<j,ti<tj,如果能输出YES,并输出其划分段数和划分的内容。
This morning Tolik has understood that while he was sleeping he had invented an incredible problem which will be a perfect fit for Codeforces! But, as a "Discuss tasks" project hasn't been born yet (in English, well), he decides to test a problem and asks his uncle. After a long time...

Please note that the counter always shows two digits. Input The only line of input contains exactly two digits representing number n (0 ≤ n ≤ 99). Note that n may have a leading zero. Output In the only line of the output print the number of good integers. Sample test(s)...
