A. Digits Sumtime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard outputLet's define S(x) to be the sum of digits of number x written in decimal system. For example, S(5) = 5, S(10) = 1, S(322) = 7.We will call an integer x interesting if S(x + 1) < S(x). In each test you will be given one integer n. Your task is to calculate the number of integers x such that 1 \le x \le n and x is interesting.InputThe first line contains one integer t (1 \le t \le 1000)  — number of test cases.Then t lines follow, the i-th line contains one integer n (1 \le n \le 10^9) for the i-th test case.OutputPrint t integers, the i-th should be the answer for the i-th test case.ExampleInput
