Range Over Channels | Challenge

Introduction

This challenge aims to test your ability to iterate over values received from a channel using the for and range syntax in Golang.

Range Over Channels

You are required to write a function that takes in a channel of integers and returns the sum of all the integers received from the channel.

Requirements

• The function should be named sumInts.
• The function should take in a single parameter of type chan int.
• The function should return a single integer value.
• You are not allowed to use any loops or recursion inside the function body.
• You are not allowed to use any external packages.

Example

$ go run range-over-channels.go
one
two

## This example also showed that it's possible to close
## a non-empty channel but still have the remaining
## values be received.

Summary

In this challenge, you were tasked with writing a function that sums up all the integers received from a channel using the for and range syntax in Golang. By completing this challenge, you should have a better understanding of how to iterate over values received from a channel and how to use goroutines to receive values from a channel.
