Solution:

We can use a loop to read the input integers and calculate their sum for each pair. Then, we print the sum for each pair on a separate line.

Here's the Python code:

read the number of pairs

n = int(input())

loop over the pairs

for i in range(n): # read the pair a, b = map(int, input().split()) # calculate the sum s = a + b # print the sum print(s)

The map() function is used to convert the input string into integers, which are then assigned to variables 'a' and 'b'. The split() function is used to split the input string into two parts, which are then converted into integers using map(). Finally, the sum of 'a' and 'b' is calculated and printed.
