How to check if Two Sets are Equal in Go

How to check if Two Sets are Equal in Go ?

Answer

In Go, sets are typically implemented using maps. You can check if two sets are equal by comparing their elements.


✐ Examples

1 Check Equality of Two Sets using Maps - Equal Sets

In this example,

  1. We create two maps named set1 and set2.
  2. We add the same elements to both maps.
  3. We compare the length of both maps to ensure they have the same number of elements.
  4. We iterate over the keys of one map and check if each key exists in the other map.
  5. If all keys are found, then the sets are equal; otherwise, they are not.

Go Program

set1 := map[int]bool{1: true, 2: true, 3: true}
set2 := map[int]bool{1: true, 2: true, 3: true}

func setsAreEqual(set1, set2 map[int]bool) bool {
    if len(set1) != len(set2) {
        return false
    }
    for key := range set1 {
        if !set2[key] {
            return false
        }
    }
    return true
}

fmt.Println(setsAreEqual(set1, set2)) // Output: true

Output

true

2 Check Equality of Two Sets using Maps - Non-Equal Sets

In this example,

  1. We create two maps named set1 and set2.
  2. We add different elements to each map.
  3. We compare the length of both maps to ensure they have the same number of elements.
  4. We iterate over the keys of one map and check if each key exists in the other map.
  5. If all keys are found, then the sets are equal; otherwise, they are not.

Go Program

set1 := map[int]bool{1: true, 2: true, 3: true}
set2 := map[int]bool{4: true, 5: true, 6: true}

func setsAreEqual(set1, set2 map[int]bool) bool {
    if len(set1) != len(set2) {
        return false
    }
    for key := range set1 {
        if !set2[key] {
            return false
        }
    }
    return true
}

fmt.Println(setsAreEqual(set1, set2)) // Output: false

Output

false
