Well, you already asked about two in a very short time, and two very easy ones at that. So it is not a stretch to expect more to come. One would think that the forum on the site where you do the challenges is a better place to ask, also because that way we don’t have to figure out if the owners/community appreciate you asking these questions here.
I believe I already suggested an alternative to use. Doing things manually is probably the best way to go on these challenges (unless it is specifically the point to use some tool).
When asking for help, it would also be useful to give more information on things (e.g. what you have tried so far). Just stating you couldn’t do it doesn’t give a lot to work with. Also, try forming proper sentences. Like with punctuation and stuff. It helps other people understand you.
