Third Friend Sum

You are given two integers x and y which represent the numbers chosen by two of three friends. The third friend always picks the number 4. Your task is to compute and output the sum of all three numbers.

The mathematical formula is given by:

$$S = x + y + 4$$

Example: For an input of 5 3, the output should be 12 because \(5 + 3 + 4 = 12\).

inputFormat

The input consists of a single line containing two space-separated integers x and y.

Input is to be read from standard input (stdin).

outputFormat

Output a single integer, which is the sum computed using the formula \(S = x + y + 4\), to standard output (stdout).
