# Task
Given two integers `a` and `b`, return the sum of the numerator and the denominator of the reduced fraction `a/b`.
# Example
For `a = 2, b = 4`, the result should be `3`
Since `2/4 = 1/2 => 1 + 2 = 3`.
For `a = 10, b = 100`, the result should be `11`
Since `10/100 = 1/10 => 1 + 10 = 11`.
For `a = 5, b = 5`, the result should be `2`
Since `5/5 = 1/1 => 1 + 1 = 2`.
# Input/Output
- `[input]` integer `a`
The numerator, `1 ≤ a ≤ 2000`.
- `[input]` integer `b`
The denominator, `1 ≤ b ≤ 2000`.
- `[output]` an integer
The sum of the numerator and the denominator of the reduces fraction.
