Solution for IX and X Does your solution look like this: package main func roman(number int) string { result := "" if number >= 10 { result = "X" number = number - 10 } if number >= 9 { result = "IX" number = number - 9 } if number >= 5 { result = "V" number = number - 5 } if number == 4 { result = "IV" number = number - 4 } for i := 0; i < number; i++ { result += "I" } return result } Do your tests look like this?

Lesson 12 Solution So yesterday you worked on converting 6, 7, and 8 to VI, VII, and VIII. Does your solution look like this? romans_test.go: func TestRoman6(t *testing.T) { result := roman(6) expected := "VI" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.", result, expected) } } func TestRoman7(t *testing.T) { result := roman(7) expected := "VII" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.

Lesson 11 Solution Yesterday you were supposed to add a unit test and code for the roman numeral 5. Did you come up with this? Unit Test: func TestRoman5(t *testing.T) { result := roman(5) expected := "V" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.", result, expected) } } Run the Test Did you remember to run the test first before trying to solve it? go test --- FAIL: TestRoman5 (0.

Lesson 10 Solution: Roman Numeral 4 Did you get a solution that looks something like this? func roman(number int) string { result := "" if number == 4 { return "IV" } for i := 0; i < number; i++ { result += "I" } return result } or did you get a solution that looks like this? package main func roman(number int) string { result := "" if number == 4 { result = "IV" number = number - 4 } for i := 0; i < number; i++ { result += "I" } return result } Either way works:

Lesson 9 Solution: Refactoring Yesterday’s exercise was to see if you could figure out a way to refactor our code so far. In other words, we wanted to see if we could simplify this code: func roman(number int) string { if number == 3 { return "III" } if number == 2 { return "II" } return "I" } The way we do this is with a loop. A loop lets us repeat things over and over and is one of the fundamental tools of programming.

Lesson 8 Solution: Roman Numeral III Yesterday’s exercise was to get to roman numeral III. Did you get something like this? roman.go func roman(number int) string { if number == 3 { return "III" } if number == 2 { return "II" } return "I" } roman_test.go package main import ( "testing" ) func TestRoman1(t *testing.T) { result := roman(1) expected := "I" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.

Lesson 7 Solution: Roman Numeral II If you completed lesson 7, you should have gotten something like the following. Remember, there is no one correct way to program any more than there is one right way to write a story or paint a picture. If you came up with a slightly different solution but it passes your unit tests, awesome!!! roman_test.go func TestRoman1(t *testing.T) { result := roman(1) expected := "I" if result !

Lesson 6 Solution: Roman Numeral I You should have come up with a solution that looks like the following. If you did, great! All it took was changing: return "" to return “I” roman.go func roman(number int) string { return "I" } roman_test.go func TestRoman(t *testing.T) { result := roman(1) expected := "I" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.", result, expected) } } go test PASS ok hello 0.

Recap of progress to date So far you’ve learned some basics of writing code. We haven’t talked about terms, but you’ve learned how to compile and format code, how to create functions, how to define variables, how to unit test, and how to do conditional statements (aka if statements). Even more importantly, you’ve learned how to search for answers and experiment. You’ve got a lot of the building blocks for coding.

Session 4 Solution: hello_test.go func TestHelloInigoMontoya(t *testing.T) { result := hello("inigo montoya") expected := "hello, inigo montoya" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.", result, expected) } } func TestHelloDuaLipa(t *testing.T) { result := hello("Dua Lipa") expected := "hello, Dua Lipa" if result != expected { t.Errorf("result was incorrect, got: %v, want: %v.", result, expected) } } func TestHelloDarthVader(t *testing.T) { result := hello("Darth Vader") expected := "hello, Darth Vader" if result !

My experience with ADHD has been that slow consistent progress is how I achieve lasting results. When I hyperfocus on a new interest, I tend to burn out after a month or two and never touch it again. So this course is an attempt to go back and document how I wished someone had taught me to program. It literally took me years of trying before I felt comfortable programming professionally.

Yesterday’s solution: package main import "fmt" func main() { fmt.Println("hello world") } When you run it you should be able to see it work like this: go run hello, world If you weren’t able to get this going on your own, go back until you can create this from memory and understand the pieces. Hint: you may have to run a command like this if you’re getting errors about go.mod:

Lesson 2: Write Your First Program, aka Hello, World So yesterday we learned how to install golang. If you haven’t done that yet, go do that. Goals Today: write your first go program. build the habit of spending 5 minutes a day learning. Let’s get started: In this course I’m going to spend most of my time giving high level directions and trust your ADHD will take you down rabbit holes as you get curious about things.

Lesson 1: Set up General rules for this course: Commit to at least 5 minutes a day. Figuring things out on your own is better than being given the answers. The general idea is, instead of spending hours following along typing what you see on a YouTube video and then realizing you retain none of it, each lesson will be a small programming puzzle to solve that gets you along the way to being a programmer.

Solution for IX and X Does your solution look like this: package main func roman(number int) string { result := "" if number >= 10 { result = "X" number = number - 10 } if number >= 9 { result = "IX" number = number - 9 } if number >= 5 { result = "V" number = number - 5 } if number == 4 { result = "IV" number = number - 4 } for i := 0; i < number; i++ { result += "I" } return result } Do your tests look like this?
