Step by Step solution about How to resolve the algorithm Write entire file step by step in the Ruby programming language

The code snippet you provided is in Ruby and it opens a file (fname) for writing ('w') and then writes a string (str) to it using the write method. This code will create a new file if it doesn't exist, or it will overwrite the existing file if it does exist. The open method takes a filename and a mode as arguments, where the mode can be one of the following: 'r' open for reading 'w' open for writing; truncates existing file 'a' open for appending; existing data is preserved 'r+' open for reading and writing; file must exist 'w+' open for reading and writing; truncates existing file 'a+' open for reading and appending; existing data is preserved The write method takes a string as an argument and writes it to the file. The open method returns a file object that can be used to read or write to the file. The f variable in the code snippet is a file object that is used to write to the file. The {|f| ... } block is a block that is executed with the file object as the parameter. The f.write(str) line writes the string str to the file. The open method closes the file automatically when the block finishes executing.

open(fname, 'w'){|f| f.write(str) }
