Step by Step solution about How to resolve the algorithm Anagrams step by step in the Go programming language

The provided Go program finds and prints all the words in a given text file that have the most unique characters.

A step-by-step explanation of the program:

1. http.Get: It retrieves the content of a file from a URL. In this case, it fetches unixdict.txt from wiki.puzzlers.org.

2. ioutil.ReadAll: It reads the content of the HTTP response body into a byte slice b.

3. bs: It defines a custom type byteSlice that implements the sort.Interface interface for sorting byte slices. This type is used to sort the characters of each word alphabetically.

4. m: It creates a map m that maps a sorted character sequence to a slice of words that have that character sequence.

5. for Loop:

   • It iterates over the bytes in b and constructs a new byteSlice bs for each word.
   • It sorts bs and converts it back to a string k.
   • It checks if there are any words mapped to k in the m map. If not, it appends a new slice a to m[k]. Otherwise, it appends the word to the existing a slice.
   • It keeps track of the maximum number of words (ma) that have the most unique characters.

6. After processing all the words, it iterates through the values of m and prints the words that have the maximum number of unique characters.

In summary, this program takes a text file, finds all the words that have the most unique characters, and prints those words. The custom byteSlice type and the sorting of character sequences are used to efficiently determine which words have the most unique characters.

    }
    b, err := ioutil.ReadAll(r.Body)

        sort.Sort(bs)
        k := string(bs)
        a := append(m[k], word)
        if len(a) > ma {
            ma = len(a)
        }
        m[k] = a
    }
    for _, a := range m {
        if len(a) == ma {
            fmt.Printf("%s\n", a)
        }
    }
}

type byteSlice []byte

func (b byteSlice) Len() int           { return len(b) }
func (b byteSlice) Swap(i, j int)      { b[i], b[j] = b[j], b[i] }
func (b byteSlice) Less(i, j int) bool { return b[i] < b[j] }
