# Help me in solving DIFFSUM problem

### My code

``````# cook your dish here
a = int(input())
b = int(input())
if a > b:
print( a - b )
else:
print( a + b )

``````

The problem here is that the input comes in one line e.g. “82 28”. Therefore when you set `a = int(input())`, you are essentially saying `a = int("82 28")`, which cannot be type casted. Instead, you should use the following syntax: `a, b = map(int, input().split())`. Breaking this down:

• `input().split()`, for the test-case results in: [“82”, “28”].
• Then the `map()` function take each element in the list above, casts those elements as `int` (specified by the `int` keyword passed to `map()`) and then assigns each element to the respective variables in this case `a` and `b`.

This syntax allows you to take a single line input and assign it to multiple variables.

Here is the working code using this method:

``````a, b = map(int, input().split())
if a > b:
print(a - b)
else:
print(a + b)
``````

#include <stdio.h>

int main(void) {
