4) Write the function "public boolean teststrings(String stringone, string stringTwo)" that will: - first, remove all zero characters in stringone and stringTwo - finally, return true if the last two characters of the modified strings stringone and StringTwo are the same StringTwo are the same return false otherwise return false otherwise You can assume that both strings have more than tw Examples: o non-zero characters. teststrings ("1234567", "1267") will return true teststrings ("00012300456070" "012006000700") will return true teststrings ("1234567", "12671") will return false teststrings ("00012300456070" "000120065000700") will return false
