Several algorithms for deduplication of golang string slices

The function of the function is to remove duplicate elements from the input string slice and return the result after deduplication. The specific implementation logic is as follows:

• Create an empty result sliceresult, used to store deduplicated strings.
• Create a temporary maptempMap, used to store non-repeat strings. The key of the map is a string and the value is byte type.
• Iterate through the input string sliceslcEach element ine：
  • First, gettempMaplength and assign it to variablel。
  • Then, turn the stringeAs a key, the value is set to 0 and storedtempMapmiddle.
  • If you jointempMapback,tempMapThe length of the element that did not exist was successfully added (that is, the element that did not exist was successfully added), which means that the element appeared for the first time and was not repeated.
    • Put this elementeAppend to result sliceresultmiddle.
• After traversing all elements, return the result sliceresult, that is, the result after removing the weight.

// Filter duplicate elements through the unique feature of map primary keyfunc RemoveDuplicateStrings(strs []string) []string {
    result := []string{}
    tempMap := map[string]byte{} // Store non-repeat strings    for _, e := range strs {
        l := len(tempMap)
        tempMap[e] = 0
        if len(tempMap) != l { // After adding map, the map length changes, the elements will not be repeated            result = append(result, e)
        }
    }
    return result
}
