Hey Blind4Basics, I don't want to offend you personally and so would I urge you not to either. But I'll describe what made me downvote yesterday.

okay let me emphasize that every randomly generated testcase has a wrong solution. Here you have another example:
([points],[given solution],[Real convex hull]):
([[96, 56], [48, 33], [17, 73], [57, 7], [14, 17], [31, 46], [54, 47], [48, 95], [89, 96], [75, 15], [96, 87], [33, 69], [17, 41], [76, 97], [75, 99], [77, 20], [57, 52], [90, 41], [96, 83], [42, 26], [66, 84], [26, 33], [28, 45], [59, 76], [44, 9], [45, 53], [22, 33], [31, 62], [31, 94], [49, 92], [76, 60], [40, 37], [41, 70], [98, 18], [29, 78], [80, 25], [60, 6], [81, 56], [82, 24], [56, 26], [16, 83], [88, 75], [57, 9], [62, 7], [72, 12], [93, 48], [24, 79], [97, 17], [27, 41], [91, 44]],[[14, 17], [16, 83], [31, 94], [44, 9], [60, 6], [75, 99], [89, 96], [96, 87], [97, 17]],[[14, 17], [16, 83], [31, 94], [44, 9], [60, 6], [75, 99], [89, 96], [96, 87], [97, 17], [98, 18]])

Random test solutions appear to be wrong (python). one point is always missing, which belongs to the convex hull.
e.g. ([points],[given solution],[Real convex hull]): ([[86, 42], [78, 14], [68, 22], [25, 66], [94, 10], [6, 40], [30, 9], [14, 63], [12, 80], [36, 60], [28, 15], [67, 39], [31, 36], [38, 76], [9, 49], [29, 59], [8, 70], [98, 83], [80, 96], [63, 27], [74, 10], [79, 69], [59, 9], [42, 80], [81, 59], [19, 39], [48, 35], [92, 34], [70, 33], [72, 84], [51, 56], [85, 56], [49, 66], [41, 95], [54, 43], [72, 64], [98, 82], [36, 30], [53, 22], [83, 27], [5, 52], [72, 21], [53, 88], [44, 33], [33, 81], [32, 21], [79, 8], [24, 80], [25, 97], [68, 19]],[[5, 52], [6, 40], [8, 70], [12, 80], [25, 97], [30, 9], [79, 8], [80, 96], [94, 10], [98, 82]],[[5, 52], [6, 40], [8, 70], [12, 80], [25, 97], [30, 9], [79, 8], [80, 96], [94, 10], [98, 82], [98, 83]])
