Nested loops in Go - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print numbers from 1 to 3 using a loop.

Go

for i := 1; i <= [1]; i++ {
    fmt.Println(i)
}

Drag options to blanks, or click blank then click option'

A0

B5

C3

D10

Attempts:

3 left

💡 Hint

Common Mistakes

Using 0 or 10 instead of 3 in the loop condition.

Forgetting to use <= instead of <.

The loop should run from 1 to 3, so the condition is i <= 3.

2fill in blank

medium

Complete the code to print a 3x3 grid of stars using nested loops.

Go

for i := 0; i < 3; i++ {
    for j := 0; j < [1]; j++ {
        fmt.Print("*")
    }
    fmt.Println()
}

Drag options to blanks, or click blank then click option'

C4

D2

Attempts:

3 left

💡 Hint

Common Mistakes

Using a different number than 3 for the inner loop.

Using <= instead of < causing extra stars.

Both loops should run 3 times to create a 3x3 grid.

3fill in blank

hard

Fix the error in the nested loops to print numbers 1 to 3 in each row.

Go

for i := 1; i <= 3; i++ {
    for j := 1; j <= [1]; j++ {
        fmt.Print(j, " ")
    }
    fmt.Println()
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 5 or 4 causing extra numbers.

Using 0 causing no output.

The inner loop should run from 1 to 3 to print numbers 1, 2, 3 in each row.

4fill in blank

hard

Fill both blanks to create a multiplication table from 1 to 3.

Go

for i := 1; i <= [1]; i++ {
    for j := 1; j <= [2]; j++ {
        fmt.Printf("%d ", i*j)
    }
    fmt.Println()
}

Drag options to blanks, or click blank then click option'

D2

Attempts:

3 left

💡 Hint

Common Mistakes

Using different numbers for the two loops.

Using numbers larger than 3 causing bigger tables.

Both loops should run from 1 to 3 to create a 3x3 multiplication table.

5fill in blank

hard

Fill all three blanks to print a right triangle of stars with 3 rows.

Go

for i := 1; i <= [1]; i++ {
    for j := 1; j <= [2]; j++ {
        if j <= [3] {
            fmt.Print("*")
        }
    }
    fmt.Println()
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using j instead of i in the if condition.

Using wrong loop limits causing incorrect triangle size.

The outer and inner loops run 3 times. The if condition prints stars up to the current row number i.
