In the online judge system, the inputs come from "standard input". To read the data from standard input, we can use a function called "input()".

>>in_line = input()

[Note 1]However, the input() function will only give you one single line of input (from standard input). To split the data from a single line, we need a function called "split()" to help.

>> inputs = in_line.split()
>> print(inputs[0], inputs[1])

[Note 2]Even we have successfully split the data, the data is still in "string" format. To do our math calculation, we need to convert the string into integer by a function called "int()".

>>a = int(inputs[0])
>> b = int(inputs[1])
