Each input file contains one test case. Each case contains a pair of integers a and b where −10的6次方≤a,b≤10的6次方
​​ . The numbers are separated by a space.

Output Specification:
For each test case, you should output the sum of a and b in one line. The sum must be written in the standard format.

解题思路：
数字的格式化输出
format(x, ‘,’) 表示指定逗号位数字的千分位分隔符

代码：

a, b = map(int, input().split())
print(format(a+b, ','))
