Reverse a string in Go

package main

	l := len(st)

	/**
	* The idea is to iterate over the half of a string and exchange
	* characters from one end to another.
	* "stash" variable used to store a character of an iteration
	*
	*       stash
	*    /  /    ^  ^
	*   /  /      \  \
	* h | e | l | l | o

	// Devide the string lenght on half (sort of)
	it := l >> 1 // faster devision ?

	fmt.Printf("Iterations: %d\n", it)

	var stash byte

	for i := it - 1; i >= 0; i-- {
		stash = st[i]     // stashing
		st[i] = st[l-1-i] // last become first
		st[l-1-i] = stash // first become last
	}

	fmt.Printf("Result: %s", st)
  
  // Result
  // Iterations: 21
