Compute SHA256 Hashes in Go (Challenge)

Introduction

This challenge aims to demonstrate how to compute SHA256 hashes in Go. SHA256 hashes are commonly used to compute short identities for binary or text blobs.

SHA256 Hashes

Given a string, compute its SHA256 hash.

Requirements

The program should import the crypto/sha256 and fmt packages.
The program should use the sha256.New() function to create a new hash.
The program should use the Write function to write the bytes of the string to the hash.
The program should use the Sum function to get the finalized hash result as a byte slice.
The program should print the original string and the hash result in hexadecimal format.

Example

## Running the program computes the hash and prints it in
## a human-readable hex format.
$ go run sha256-hashes.go
sha256 this string

## You can compute other hashes using a similar pattern to
## the one shown above. For example, to compute
## SHA512 hashes import `crypto/sha512` and use
## `sha512.New()`.

## Note that if you need cryptographically secure hashes,
## you should carefully research
## [hash strength](https://en.wikipedia.org/wiki/Cryptographic_hash_function)!

Summary

This challenge demonstrated how to compute SHA256 hashes in Go using the crypto/sha256 package. By following the requirements and completing the TODO section, the program can compute the SHA256 hash of a given string.
