Write a program to take two numbers as input and print their difference if the first number is greater than the second number otherwise$otherwise$ print their sum.

-----Input:-----
- First line will contain the first number (N1$N1$)
- Second line will contain the second number (N2$N2$)

-----Output:-----
Output a single line containing the difference of 2 numbers (N1−N2)$(N1 - N2)$ if the first number is greater than the second number otherwise output their sum (N1+N2)$(N1 + N2)$.

-----Constraints-----
- −1000≤N1≤1000$-1000 \leq N1 \leq 1000$
- −1000≤N2≤1000$-1000 \leq N2 \leq 1000$

-----Sample Input:-----
82
28

-----Sample Output:-----
54
