User Input

In Textio, users can set their profile status to communicate their current activity to those that choose to read it... However, there are some restrictions on what these statuses can contain. Your task is to implement a function that validates a user's status update. The status update cannot be empty and must not exceed 140 characters.

Assignment

Complete the validateStatus function. It should return an error when the status update violates any of the rules:

• If the status is empty, return an error that reads status cannot be empty.

• If the status exceeds 140 characters, return an error that says status exceeds 140 characters.

status.go

package status

import "errors"

// validateStatus returns an error if the provided status is invalid.
// - empty status -> error "status cannot be empty"
// - status longer than 140 chars -> error "status exceeds 140 characters"
func validateStatus(s string) error {
	if len(s) == 0 {
		return errors.New("status cannot be empty")
	}
	if len(s) > 140 {
		return errors.New("status exceeds 140 characters")
	}
	return nil
}
