Sometimes we need to segment the page, that is, to group. The base class is Uisegmentedcontrol, and its properties are shown below:Basically is a few paragraphs, paragraph of the title, each paragraph of the image. Now let's drag a segment, the

Control flowUse if and switch as conditional controls. Use For-in, for, while, and do-while as loops. The parentheses are not required, but the main braces are required.Let individualscores = [75, 43, 103, 87, 12]var Teamscore = 0For score in
