strings.Replace calls with the replace count 0 instead of -1.
The count argument for how many times a string should be replaced should not be 0
as it will not replace anything and make the function call redundant. Use -1 instead.
Example:
a := strings.Replace("SSS", "S", "H", 0) // replaces nothing
b := strings.Replace("SSS", "S", "H", -1) // replaces all S occurrences with H
