  • Greater than the previous one

    Imagine you have been uploading videos to youtube. You would like to know which videos have been greater than the previous ones. For each video, you know how many people have watched them in the first week of uploading them. Now you would like to compute the number of videos that have worked out better than the previous one you’ve uploaded.
    The first line of the input contains the number of videos n. The next n lines contain the view counts per each video for the first week of views after uploading.
    The output should contain a single number - the number of videos that have performed better than their immediate predecessor.
