Solution: Write Code with Worker Pool Pattern

Check the solution to the challenge of writing code using the worker pool pattern.

We'll cover the following

Problem breakdown

LLet’s break down the question and write the code step by step. We’re provided with the structs. Now, let’s initialize buffer channels with a capacity of 10.

jobs := make(chan Job, 10)
results := make(chan Result, 10)

Write a function to calculate the sum of digits. For this, we’ll need a little bit of algorithmic knowledge. Initialize sum to 0. Take the integer and perform the modulo operation with 10. The operation will return the last digit. Keep dividing the quotient by 10 until the quotient is 0. In each iteration, add the remainder in the sum.
