题目描述

You are given a decimal representation of an integer xx without leading zeros.

You have to perform the following reduction on it exactly once: take two neighboring digits in xx and replace them with their sum without leading zeros (if the sum is 00 , it's represented as a single 00 ).

For example, if x=10057x = 10057 , the possible reductions are:

  • choose the first and the second digits 11 and 00 , replace them with 1+0=11+0=1 ; the result is 10571057 ;
  • choose the second and the third digits 00 and 00 , replace them with 0+0=00+0=0 ; the result is also 10571057 ;
  • choose the third and the fourth digits 00 and 55 , replace them with 0+5=50+5=5 ; the result is still 10571057 ;
  • choose the fourth and the fifth digits 55 and 77 , replace them with 5+7=125+7=12 ; the result is 1001210012 .

What's the largest number that can be obtained?

输入格式

The first line contains a single integer tt ( 1t1041 \le t \le 10^4 ) — the number of testcases.

Each testcase consists of a single integer xx ( 10x<1020000010 \le x < 10^{200000} ). xx doesn't contain leading zeros.

The total length of the decimal representations of xx over all testcases doesn't exceed 21052 \cdot 10^5 .

输出格式

For each testcase, print a single integer — the largest number that can be obtained after the reduction is applied exactly once. The number should not contain leading zeros.

说明/提示

The first testcase of the example is already explained in the statement.

In the second testcase, there is only one possible reduction: the first and the second digits.
