Correct answer will be upvoted else downvoted.

 

number is called 2050-number if it is 2050, 20500, ..., (2050⋅10k for integer k≥0).

 

Given a number n, you are asked to represent n as the sum of some (not necessarily distinct) 2050-numbers. Compute the minimum number of 2050-numbers required for that.

 

Input

The first line contains a single integer T (1≤T≤1000) denoting the number of test cases.

 

The only line of each test case contains a single integer n (1≤n≤1018) denoting the number to be represented.

 

Output

For each test case, output the minimum number of 2050-numbers in one line.

 

If n cannot be represented as the sum of 2050-numbers, output −1 instead.
