Calculate a+B and output the sum in standard format – that's, the digits must be Separat Ed to groups of three by commas (unless there is less than four digits). Input Specification:Each input file contains the one test case. Each case contains a pair of integers A and b where ? The numbers is separated by a space. Output Specification:For each test case, you should output the sum of A and B on one line. The sum must is written in the standard format.Sample Input:-1000000 9Samp

Learned a lemma: under the condition of satisfying s minimization, there must be a scheme to construct sequence B, so that the values in sequence B are derived from a. (Mathematical inductive method + median theorem)For the state of the expression, there must first be an I, to select the number of the first of the corresponding optimal solution, because of the need to maintain the sequence monotonicity, it is necessary to add a factor j in the state, indicating that in the first place after the
