题目描述

Alice has just learned addition. However, she hasn't learned the concept of "carrying" fully — instead of carrying to the next column, she carries to the column two columns to the left.

For example, the regular way to evaluate the sum 2039+29762039 + 2976 would be as shown:

However, Alice evaluates it as shown:

In particular, this is what she does:

  • add 99 and 66 to make 1515 , and carry the 11 to the column two columns to the left, i. e. to the column " 00 99 ";
  • add 33 and 77 to make 1010 and carry the 11 to the column two columns to the left, i. e. to the column " 22 22 ";
  • add 11 , 00 , and 99 to make 1010 and carry the 11 to the column two columns to the left, i. e. to the column above the plus sign;
  • add 11 , 22 and 22 to make 55 ;
  • add 11 to make 11 .

Thus, she ends up with the incorrect result of 1500515005 .Alice comes up to Bob and says that she has added two numbers to get a result of nn . However, Bob knows that Alice adds in her own way. Help Bob find the number of ordered pairs of positive integers such that when Alice adds them, she will get a result of nn . Note that pairs (a,b)(a, b) and (b,a)(b, a) are considered different if aba \ne b .

输入格式

The input consists of multiple test cases. The first line contains an integer tt ( 1t10001 \leq t \leq 1000 ) — the number of test cases. The description of the test cases follows.

The only line of each test case contains an integer nn ( 2n1092 \leq n \leq 10^9 ) — the number Alice shows Bob.

输出格式

For each test case, output one integer — the number of ordered pairs of positive integers such that when Alice adds them, she will get a result of nn .

说明/提示

In the first test case, when Alice evaluates any of the sums 1+91 + 9 , 2+82 + 8 , 3+73 + 7 , 4+64 + 6 , 5+55 + 5 , 6+46 + 4 , 7+37 + 3 , 8+28 + 2 , or 9+19 + 1 , she will get a result of 100100 . The picture below shows how Alice evaluates 6+46 + 4 :
