NEED HELP ASAP!!! doLikeTweet This function is used to add a "like" to the the currently selected tweet. The function receives as parameters, the timeline containing the tweet, the current number of tweets in the timeline, and the position number in the timeline of the currently selected tweet. For safety, the function should first verify that the selected parameter is actually a valid position within the used portion of the array. If it isn't the function should print the message: No tweet is selected.
