各位大佬們我想問一下python 要怎麼寫出能自由輸入數字的 selection sort
不能使用 sort 的情況下

def SORT(*args, reverse = False): arr = list(args) res = arr[:] if(not reverse): for n in range(len(res)): t = min(res[n:]) i = res.index(t) if res[n] != t: res[n] -= res[i] res[i] += res[n] res[n] = res[i] - res[n] else: for n in range(len(res)): t = max(res[n:]) i = res.index(t) if res[n] != t: res[n] -= res[i] res[i] += res[n] res[n] = res[i] - res[n] return res A = SORT(13, 5, 78, 9, 55) B = SORT(13, 5, 78, 9, 55, reverse = True) print(*A) print(*B)

就是選擇排序而已只是要能夠自己輸入數字
