hdu 5867 Water problem

Problem Description

If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3+3+5+4+4=19 letters used in total.If all the numbers from 1 to n (up to one thousand) inclusive were written out in words, how many letters would be used?

Do not count spaces or hyphens. For example, 342 (three hundred and forty-two) contains 23 letters and 115 (one hundred and fifteen) contains 20 letters. The use of "and" when writing out numbers is in compliance with British usage.

 

Input

There are multiple test cases. The first line of input contains an integer T, indicating the number of test cases.

For each test case: There is one positive integer not greater one thousand.

 

Output

For each case, print the number of letters would be used.

 

Sample Input

3123

 

Sample Output

3611
就是算从1到n的数字用英文拼，要用多少字母；
打表就行。
不打表也不会超时。
注意临界，以下两种打个表。
1.十位数的前二十个数字。
2.十位数的整数。
硬加一遍就行了。
