o)For the given strings, replace last but third so with X. Only print the lines which are changed by the substitution.
$ printf 'so and so also sow and soup' | awk ##### add your solution here so and X also sow and soup $ printf 'sososososososo\nso and so\n' | awk ##### add your solution here sososoXsososo
