convert slice to unique slice golang

To convert a slice to a unique slice in Go, you can follow these steps:

1. Create an empty map with the slice element type as the key type and a boolean as the value type. This map will be used to track unique elements in the slice.

2. Iterate over the original slice using a for loop.

3. Check if the current element exists in the map by using the map's key. If the element is not in the map, add it as a key with a value of true.

4. Create a new empty slice with the same element type as the original slice. This new slice will hold the unique elements.

5. Iterate over the original slice again and check if each element exists in the map. If it does, add it to the new slice.

6. The new slice will now contain only the unique elements from the original slice.

Here is an example of how you can implement this in Go:

func UniqueSlice(slice []int) []int {
    uniqueMap := make(map[int]bool)

    for _, val := range slice {
        uniqueMap[val] = true
    }

    uniqueSlice := make([]int, 0, len(uniqueMap))

    for key := range uniqueMap {
        uniqueSlice = append(uniqueSlice, key)
    }

    return uniqueSlice
}

In this example, the UniqueSlice function takes a slice of integers as input and returns a new slice containing only the unique elements. It uses a map to keep track of unique elements and then constructs a new slice based on the unique keys in the map.
