Instructions

Write a program that takes 3 arguments, the first argument is a string in which to replace a letter (the 2nd argument) by another one (the 3rd argument).

  • If the number of arguments is different from 3, the program displays nothing.

  • If the second argument is not contained in the first one (the string) then the program rewrites the string followed by a newline ('\n').

Usage

$ go run . "hella there" "a" "o"
hello there
$ go run . "abcd" "z" "l"
abcd
$ go run . "something" "a" "o" "b" "c"
$
