Go Channels and Declarations | Dataford Interview Questions

What is a Go channel and how is it declared?

Implement go_channel_declaration(channel_type, capacity) to return a valid Go declaration using make. Use an unbuffered declaration when capacity is 0; otherwise, include the buffer capacity.

Input: a type name and a non-negative integer capacity. Output: the corresponding Go declaration as a string.

Examples:

("int", 0) returns "ch := make(chan int)" because zero capacity creates an unbuffered channel.
("string", 3) returns "ch := make(chan string, 3)" because the channel has a buffer of three values.

Constraints

1 <= len(channel_type) <= 50
channel_type is a valid Go type name
0 <= capacity <= 10^9

Function Signature
