( 23037 ) B Minor Reduction PROGRAMMING greedy greedy strings strings

B"You are given a decimal representation of an integer x without leading zeros. You have to perform the following reduction on it exactly once: take two neighboring digits in x and replace them with their sum without leading zeros (if the sum is 0 , it's represented as a single 0 ). For example, if x = 10057 , the possible reductions are: What's the largest number that can be obtained? The first line contains a single integer t ( 1 <= t <= 10^4 ) -- the number of testcases. Each testcase consists of a single integer x ( 10 <= x < 10^{200000} ). x doesn't contain leading zeros. The total length of the decimal representations of x over all testcases doesn't exceed 2 cdot 10^5 . 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. 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. "...
