International Abbreviation Olympiad takes place annually starting from 1989. Each year the competition receives an abbreviation of form IAO’y, where y stands for some number of consequent last digits of the current year. Organizers always pick an abbreviation with non-empty string y that has never been used before. Among all such valid abbreviations they choose the shortest one and announce it to be the abbreviation of this year’s competition.

For example, the first three Olympiads (years 1989, 1990 and 1991, respectively) received the abbreviations IAO’9, IAO’0 and IAO’1, while the competition in 2015 received an abbreviation IAO’15, as IAO’5 has been already used in 1995.

You are given a list of abbreviations. For each of them determine the year it stands for.

Input

The first line of the input contains a single integer n (1 ≤ n ≤ 1000) — the number of abbreviations to process.

Then n lines follow, each containing a single abbreviation. It’s guaranteed that each abbreviation contains at most nine digits.

Output

For each abbreviation given in the input, find the year of the corresponding Olympiad.

【题解】



找规律；

左边对应数字范围；右边对应缩写的长度；

即缩写长度为x则在相应的左边范围内找;

这个范围很容易写出来的；

输出答案的时候每个范围也只要特判一下就能知道是具体哪个数字；

多个if用switch替代比较方便；
