uva 10112

1. 用三個 for 迴圈跑過任三點的組合



2. 再用一個 for 迴圈跑這三點以外的其他點



3. 如果第四點與選定三點之任兩點所圍三角形面積合，等於選定三點的面積，代表第四點在三角形內

ex : △abc = △abd + △acd + △bcd , d在△內



4. 如果符合條件，把面積存起來，用於之後比較面積大小



5. 面積大的取代面積小的



6. 印出面積最大三角形-Passing any combination of uva 10112 1. Three in three for loop 2 and then a for loop to run other point other than these three points 3. If any of the three points of fourth spot with a selected triangle bounded covering an area equal to three of the area selected, representing the fourth point inside the triangle ex: △ abc = △ abd+ △ acd+ △ bcd, d in △ 4. If eligible, the area to save up for later comparison 5. A large area the size of a small area of 6. replace print the largest triangle
