Fill both blanks to create a map of words to their lengths for words longer than 3 characters.

Go

package main

import "fmt"

func main() {
    words := []string{"go", "code", "fun", "learn"}
    lengths := map[string]int{}
    for _, word := range words {
        if len(word) [1] 3 {
            lengths[word] = [2]
        }
    }
    fmt.Println(lengths)
}

💡 Hint

Common Mistakes

Using '<' instead of '>' for length comparison.

Assigning the word instead of its length.

The condition len(word) > 3 checks word length. The value len(word) stores the length.

5fill in blank

hard

Fill all three blanks to create a map with uppercase keys and values greater than 2.

Go

package main

import (
    "fmt"
    "strings"
)

func main() {
    data := map[string]int{"go": 1, "code": 4, "fun": 3}
    result := map[string]int{}
    for k, v := range data {
        if v [3] 2 {
            result[[1]] = [2]
        }
    }
    fmt.Println(result)
}

💡 Hint

Common Mistakes

Using the key instead of uppercase key.

Using '<' instead of '>' in condition.

We check if v > 2. Then store the value v with the uppercase key strings.ToUpper(k).
