寫一程式，讓使用者可以輸入四組數對，分別代表四個點座標，且其輸入順序依

序為順時鐘方向之四個端點，程式則依據輸入的四個座標判斷其形狀，可能的形

狀為square(正方形)、rectangle(長方形)、diamond(菱形)、parallelogram(平行四邊

形)及others(其他)，且輸出結果必須為最適合之答案。-Write a program that allows users to enter the number on the four groups, representing the coordinates of four points, and the input sequence order of the four endpoints clockwise direction, the program is based on the input of the four coordinates to determine the shape, may be the shape of the square (square), rectangle (rectangle), diamond (diamond), parallelogram (parallelogram) and others (other), and the output must be the most suitable answer.
