I have written a LZW decoder algorithm in Go for a programming task required as part of a job application. A LZW code is a sequence of integers which can be decoded as a string. I have basically written a function that looks like this:
func LZWdecoder(code []int) string {
// * perform decoding *
return decodedString
}
They have provided me with a .z file which is encoded using LZW encoding so I can test my algorithm on it (it decodes to human readable text).
However, I don't know how to "load" that file into an integer slice that I can run through my function. Any help would be greatly appreciated.
Use import os then os.ReadFile("filename.z") should return a slice of bytes, which you can then convert to a slice of int using the method described here: Convert byte slice to int slice
